                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS


                        SCHEDULED FOR DECEMBER 8, 2004


To the Shareholders of the Funds:


     A joint special meeting of shareholders (the "Meeting") for each of the
Safeco Funds will be held at the offices of Safeco Mutual Funds, King
Auditorium, 4854 154th Place, N.E., Redmond, WA 98052 on December 8, 2004 at
2:00 p.m., local time, to consider the following:

  1. With respect to each Safeco Fund, a proposal to approve an Agreement and
     Plan of Reorganization. Under the Agreement and Plan of Reorganization,
     your Safeco Fund will transfer all of its assets to an investment company
     (each a "Pioneer Fund") managed by Pioneer Investment Management, Inc.
     ("Pioneer") in exchange for Investor Class shares of the Pioneer Fund. The
     Pioneer Fund also will assume your Safeco Fund's liabilities that are
     included in the calculation of your Safeco Fund's net assets at the
     closing. Generally, each Pioneer Fund is an existing mutual fund with a
     substantially similar investment objective and similar investment policies
     as your Safeco Fund. In the case of certain Safeco Funds, the Pioneer Fund
     is a newly organized mutual fund with a substantially similar investment
     objective and similar investment policies as your Safeco Fund. Holders of
     all share classes of your Safeco Fund will receive Investor Class shares of
     the corresponding Pioneer Fund. Investor Class shares of the applicable
     Pioneer Fund will be distributed to shareholders in proportion to the
     relative net asset value of their share holdings on the closing date of the
     reorganization. Following the reorganization, your Safeco 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. With respect to each Safeco Fund, a proposal to approve an interim
    investment advisory agreement between your Safeco Fund and Pioneer.
    Pioneer has provided advisory services for your Safeco Funds pursuant to
    this agreement since August 2, 2004, when the advisory agreement between
    your Safeco Fund and Safeco Asset Management Company terminated. Approval
    of the interim investment advisory agreement will enable Pioneer to
    receive advisory fees currently held in escrow. Your Board of Trustees
    recommends that you vote FOR this proposal.

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

     Shareholders of record as of the close of business on October 8, 2004, 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 Safeco Fund may be required to make additional
solicitations.


                                                By order of the Boards of
Trustees,

                                                [Name]

Background to the Reorganizations


     Safeco Asset Management Company ("SAM"), the Safeco Funds' investment
adviser until August 2, 2004, was a subsidiary of Safeco Corporation, a
multi-line insurance company. On August 2, 2004, Symetra Financial Corporation
("Symetra") acquired certain assets from Safeco Corporation, including all of
the capital stock of SAM. While reviewing the operations of SAM in anticipation
of that transaction, Symetra determined that engaging in the business of
investment adviser to the Safeco Funds was not a core business that it intended
to continue. After investigating and discussing several alternatives for
ongoing investment management of the Safeco Funds with the Trustees, Symetra
conducted a search for a new investment adviser for the Safeco Funds.
Ultimately Symetra decided to recommend to the Boards that Pioneer Investment
Management, Inc. ("Pioneer") be hired to manage the Safeco Funds on an interim
basis until the Reorganizations occur and the Safeco Funds be reorganized into
similar mutual funds managed by Pioneer.

     The Boards met at a series of meetings in July 2004. 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 Safeco
Funds' shareholders, and the quality of the services offered by Pioneer. At
these meetings, the Trustees met with representatives of Pioneer. In addition
to these general factors, the Trustees also considered these and other factors
specifically in the context of each Reorganization. On July 30, 2004, the
Boards of Trustees, including all of the Trustees who are not interested
persons of SAM (the "Independent Trustees"), unanimously voted to approve each
of the Reorganizations. In approving the Reorganization, the Board determined
that the Reorganizations were in the best interests of the Safeco Funds'
shareholders and the interests of existing Safeco Funds' shareholders will not
be diluted as a result of the Reorganizations.

     Pioneer believes that it can offer favorable long-term investment
performance and enhanced shareholder services to the Safeco Funds'
shareholders. The Reorganizations will, by combining the assets of two mutual
funds and, by being part of a family of funds with greater distribution
capabilities, offer the potential for increased economies of scale. Increased
economies of scale have the potential of benefiting the shareholders of your
Safeco 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 Safeco 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 SAM, the investment adviser to each of the Safeco Funds until August 2,
     2004, was acquired by Symetra. Symetra informed the Board that it was not
     interested in continuing to provide investment advisory services to the
     Safeco Funds. Therefore, a change in your Safeco Fund's investment adviser
     was necessary;


   o The track record of Pioneer in managing the Pioneer Funds as compared to
     the historical performance of the Safeco Funds;

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

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


   o Pioneer's commitment until December 10, 2006, or such later date that is
     the second anniversary of the day on which each Reorganization closes (the
     "Closing Date") to limit the total operating expenses of the Investor
     Class shares of each Pioneer Fund; and

   o Shareholders who own shares in their name as of the closing of the
     Reorganization (i.e., not in the name of a broker or other intermediary)
     and maintain their account may purchase Class A shares of the
     corresponding Pioneer Fund through such account in the future or may
     exchange those shares for Class A shares of another Pioneer Fund or
     purchase Class A share of another Pioneer Fund without paying any sales
     charge. Investor Class shares will not be offered after the
     Reorganizations.

How Each Reorganization will Work

   o Safeco Fund shareholder-directed exchanges and purchases made by check,
     ACH, or wire will be accepted up until 1 p.m. (Pacific Time) on Wednesday,
     December 8, 2004. Exchange and purchase requests received after this
     deadline will be rejected and returned. Purchase and exchange requests
     made by Safeco Fund shareholders through financial institutions or
     advisers must do so earlier to ensure the trade can be processed within
     this deadline. Financial institutions and advisers that trade
     electronically (NSCC) with the Safeco Funds can place exchange and
     purchase requests up until 1 p.m. (Pacific Time) on Tuesday, December 7,
     2004.


                                       4



     Exchanges and purchases received after this deadline will be rejected and
     returned. The Safeco Funds will not process purchases made via automatic
     investment method (AIM) after December 8, 2004. Dividend/capital gain
     reinvestment and established systematic exchanges will continue through
     December 10, 2004.

   o Each Safeco Fund will transfer all of its assets to a corresponding
     Pioneer Fund. Each Pioneer Fund will assume the corresponding Safeco
     Fund's liabilities that are included in the calculation of such Safeco
     Fund's net asset value at the closing of the Reorganization (the "Closing
     Date").

   o Each Pioneer Fund will issue Investor Class shares to the corresponding
     Safeco Fund in amounts equal to the aggregate net asset value of that
     Safeco Fund's shares. Shareholders of your Safeco Fund will receive
     Investor Class 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,
     shareholders will hold the shares of the Pioneer Fund with the same
     aggregate net asset value as the shares of your Safeco Fund that you held
     immediately prior to the Reorganization.


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

   o Shares of the Investor Class of a Pioneer Fund will automatically convert
     to Class A shares of the Pioneer Fund at the end of the calendar month
     that is two years after the Closing Date.


   o Pioneer acts as investment adviser to each Pioneer Fund. Until December
     10, 2006, or such later date that is the second anniversary of the Closing
     Date, Pioneer has agreed to limit each Pioneer Fund's expenses (excluding
     extraordinary expenses) for Investor Class shares. Pioneer is not required
     to limit any expenses after the second anniversary of the Closing Date.


   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 Safeco Funds or the shareholders of the Safeco Funds.


   o In recommending each of the Reorganizations, the Trustees of your Safeco
     Fund have determined that the Reorganization is in the best interest of
     your Safeco Fund and will not dilute the interests of shareholders of your
     Safeco 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 Safeco Trust 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 after 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 fund
and institutional accounts. Pioneer or its predecessors have been managing
mutual funds since 1928 and at June 30, 2004 had, together with its affiliates,
over $35 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 Investor Class shares to be issued in the
Reorganization, each Pioneer Fund also offers Class A shares (subject to an
initial sales load and a Rule 12b-1 Plan), Class B shares (subject to a
contingent deferred sales charge and a Rule 12b-1 Plan), and 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 Y shares (which are an
institutional class of shares and are not subject to a sales charge or a Rule
12b-1 Plan) and Class R shares (which are offered only to certain retirement
plans).

Who Bears the Expenses Associated with the Reorganizations

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee's fees and out of pocket expenses
incurred as a result of the Reorganizations.


                                       5



Will Pioneer and Symetra Benefit from the Reorganizations

     Pioneer will benefit from managing a larger pool of assets. Pioneer is
also acquiring certain assets associated with SAM's mutual funds and
institutional account advisory business. In consideration for the acquisition
of these assets and certain covenants from Symetra and SAM, including their
assistance in facilitating the Reorganizations and their obligation to
indemnify Pioneer against certain liabilities, Pioneer has agreed to pay
Symetra up to $30 million. This amount is subject to downward adjustment if the
net assets of the Safeco Funds that approve the Reorganizations (together with
assets in certain other accounts) are less than $2.6 billion. Under this
agreement, Pioneer and Symetra have also agreed, among other things, that (i)
once the Investor Class converts to Class A shares, Pioneer Funds Distributor,
Inc. ("PFD"), the principal underwriter of the Pioneer Funds, shall make
payments to Safeco Securities, Inc. ("Safeco Securities"), the principal
underwriter of the Safeco Funds, pursuant to a Rule 12b-1 plan equal to 0.25%
of the average daily net assets attributable to accounts maintained by former
shareholders of the Safeco Funds; (ii) PFD will make additional continuing
payments out of its own resources to Safeco Securities, following Pioneer's
acquisition of assets from SAM, at an annual rate of 0.05% of the average daily
net assets of any Pioneer Fund held by or for the account of any former
shareholders of the Safeco Funds (including assets invested in any Pioneer Fund
as a result of the Reorganization or otherwise) and, in connection with
purchases of shares of the Pioneer Funds by former shareholders of the Safeco
Funds after the acquisition, PFD will pay out of its own resources to Safeco
Securities an amount equal to 0.20% of the amount of such purchases; and (iii)
Symetra and SAM will be subject to certain non-competition provisions.

Why is an Interim Investment Advisory Agreements being Voted On

     Having determined to recommend the Reorganizations, the Trustees elected
to appoint Pioneer as investment adviser to each Safeco Fund until the closing
of the Reorganizations given that Symetra had indicated that it did not wish to
continue to offer investment advisory services to the Safeco Funds.

     Under the Investment Company Act, shareholders must approve any new
investment advisory agreement for a Safeco Fund. However, Rule 15a-4 under the
Investment Company Act permits the Board to appoint an adviser on an interim
basis without prior shareholder approval of an investment advisory agreement
with the adviser if the new adviser agrees to provide such services on the same
terms as the previous adviser. An adviser may act on such an interim basis for
a period of 150 days. Because Pioneer will be making the payment to Symetra as
discussed above, any fees that Pioneer would be entitled to under the interim
investment advisory agreement will be held in escrow until shareholder approval
of that agreement is obtained. If shareholders of a Safeco Fund do not approve
the interim investment advisory agreement, Pioneer will not receive the fee
under the current investment advisory agreement with SAM but instead would be
paid a fee based upon Pioneer's cost in managing the Safeco Fund. If the
Reorganizations and the interim investment advisory agreements are not approved
by December 30, 2004, Pioneer will no longer provide advisory services to the
Safeco Funds, unless an extension of the 150 day period is permitted by a rule
or independent position of the staff of the SEC. If both the Reorganization and
appointment of Pioneer are approved, the interim investment advisory agreement
will continue in effect until the closing of the Reorganization.

What Happens if a Reorganization is not Approved

     If a Reorganization is not approved by shareholders, the Board will
consider what action to take. Such action could include liquidating the Safeco
Fund or seeking SEC relief to permit Pioneer to serve as investment adviser
beyond the 150-day limitation period.


Who is Eligible to Vote


     Shareholders of record on October 8, 2004 are entitled to attend and vote
at the Meeting or any adjournment of the Meeting. On each proposal, all
shareholders of a Safeco Fund, regardless of the class of shares held, will
vote together as a single 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 and the interim advisory agreement with
Pioneer. If any other business comes before the Meeting, your shares will be
voted at the discretion of the persons named as proxies.

                    Pioneer California Tax Free Income Fund

                                 PROPOSAL 1(a)


               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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco 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 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 investment adviser's judgment about the credit quality, attractiveness
     or relative value of a particular security proves to be incorrect

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     Investing in mutual fund shares is not the same as making a bank deposit.
Your investment is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. You could lose money by investing
in either Fund.


Past Performance


     Set forth below is performance information for Safeco California Tax-Free
Income Fund. The bar charts show how Safeco California Tax-Free Income 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 Safeco California Tax-Free Income Fund over
time for each class of shares (including deductions for sales charges, if
applicable) compared with a broad-based securities market index. The bar chart
gives an indication of the risks of investing in Safeco California Tax-Free
Income 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. Because Pioneer California Tax Free Income
Fund is a newly organized mutual fund, it has no past performance.

- ----------
(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer California Tax Free Income Fund through the Reorganization. In
     addition, shareholders of your Safeco Fund who own shares in their own name
     (i.e., not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer California Tax Free Income Fund or of any fund in the Pioneer
     family of funds through such account in the future without paying this
     sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     California Tax-Free Income Fund for certain fund operating expenses (but
     not all of the operating expenses of the Fund) that exceeded the rate of
     0.40% per annum of the Fund's average daily net assets. This arrangement
     included all fund operating expenses except management fees, Rule 12b-1
     fees, brokerage commissions, interest, and extraordinary expenses. In 2003,
     SAM began voluntarily reimbursing the Fund to the extent that its total
     expenses exceeded the rate of 0.86% per annum of the Fund's average daily
     net assets for Class A shares, 1.61% per annum for Class B and Class C
     shares, and 0.63% per annum for Investor Class shares. The above table
     reflects "contractual" expense reimbursements from SAM, if any, but does
     not reflect "voluntary" expense reimbursements by SAM.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer California
     Tax Free Income Fund to 0.63% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.

(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.

(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.


                                       19



9    The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

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, (e) the expense limitations are in effect for five years for Safeco
California Tax-Free Income Fund and two years for Pioneer California Tax Free
Income Fund and (f) and the Investor Class shares of Pioneer California
Tax-Free Income Fund convert to Class A shares after two years. 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 Safeco California Tax-Free Income Fund. The Trustees considered
the following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Fund until August 2, 2004, was
acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over
62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account


                                       20



options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer California Tax Free Income Fund to 0.63% of average
daily net assets. This expense ratio is lower than both the gross expenses and
expenses net of expense reimbursement of the Class A shares and lower than the
net expenses of Investor Class shares of your Safeco Fund. Although you will
experience higher expenses once the Investor Class shares convert to Class A
shares after two years, your expenses will remain the same until the second
anniversary of the Reorganization.

     Fourth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Fifth, the Investor Class shares of Pioneer California Tax Free Income
Fund received in the Reorganization will provide Safeco California TF Income
Fund shareholders with exposure to substantially the same investment product as
they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from
the Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer California Tax Free Income Fund also
considered that the Reorganization presents an excellent opportunity for the
Pioneer California Tax Free Income 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 Pioneer California Tax Free Income Fund.

     It is impossible to predict how many shares of Pioneer California Tax Free
Income Fund will actually be received and distributed by your Safeco Fund on
the Reorganization date. The table should not be relied upon to determine the
amount of Pioneer California Tax-Free Income 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer California Tax Free Income Fund,
including its Independent Trustees, approved the Reorganization. They also
determined that the Reorganization is in the best interests of Pioneer
California Tax Free Income Fund.

     The Trustees recommend that the shareholders of your Safeco 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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have a higher expenses
per share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco 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 Interest rates go up, causing the value of debt securities in the Fund's
     portfolio to decline

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

   o A downturn in equity markets causes the price of convertible securities to
     drop even when the prices of below investment grade bonds otherwise would
     not go down

     Investment in high yield securities involves substantial risk of loss.
High yield 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, an
investment in either Fund is subject to the following specific risks:

                                       29


   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

     In addition, each Fund holds a material percentage of the outstanding debt
securities of certain high yield issuers, which practice may adversely impact
the liquidity and market value of those investments. Investments in the Funds
are not bank deposits and are not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. You could lose money by
investing in either Fund.


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.


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.

     Pioneer High Yield Fund's Investor Class shares will not be outstanding
prior to the closing of the Reorganization and consequently have no performance
history. However, the performance record of the Investor Class would be
modestly higher than the performance of Class A shares due to the lower
expenses applicable to the Investor Class.

is attached as Exhibit D.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer High Yield Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer High Yield Fund or of any fund in the Pioneer family of funds
     through such account in the future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     High-Yield Bond Fund for certain fund operating expenses (but not all of
     the operating expenses of the Fund) that exceeded the rate of 0.40% per
     annum of the Fund's average daily net assets. This arrangement included all
     fund operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses. In 2003, SAM began
     voluntarily reimbursing the Fund to the extent that its total expenses
     exceeded the rate of 1.15% per annum of the Fund's average daily net assets
     for Class A shares, 1.90% per annum for Class B and Class C shares, and
     0.90% per annum for Investor Class shares. The above table reflects
     "contractual" expense reimbursements from SAM, if any, but does not reflect
     "voluntary" expense reimbursements by SAM.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer High Yield
     Fund to 0.90% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

                                       33



(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation and may be subject to higher total operating expenses.

     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, (e) the expense limitations are in effect for five years for
Safeco High-Yield Bond Fund and two years for Pioneer High Yield Fund and (f)
and the Investor Class shares of Pioneer High Yield Fund convert to Class A
shares after two years. 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 Safeco High-Yield Bond Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2,
2004, was acquired by Symetra. Symetra informed the Trustees that it did not
intend to continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the investment performance of Pioneer High Yield Fund, which has
one of the best performance records of any mutual fund specializing in high
yield securities. For the one and five year periods ended June 30, 2004, Class
A shares of Pioneer High Yield Fund had an average annual return of 11.63% and
14.31% compared to an average annual return of the Class A shares and Investor
Class shares


                                       34



of 6.42% and 11.67% (one year) and -0.42% and 0.74% (five years), 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 June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
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 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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 High Yield Fund's lower operating expenses and Pioneer's
commitment until the second anniversary of the Reorganization to limit the
expenses (excluding extraordinary expenses) of the Investor Class of Pioneer
High Yield Fund to 0.90% of average daily net assets. The estimated expenses of
the Investor Class shares of Pioneer High Yield Fund are below both the gross
expenses and expenses net of contractual expense reimbursement of each class of
shares of your Safeco Fund. Although you will experience higher expenses once
the Investor Class shares convert to Class A shares after two years, Pioneer
High Yield Fund's Class A expense ratio for the most recent fiscal year was
1.06% of average daily net assets, which was below the net expenses of the
Class A shares of your Safeco Fund and only one basis point above the net
expenses of the Investor Class of your Safeco Fund.


     Fifth, the substantially larger size of Pioneer High Yield Fund offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer High Yield Fund received in
the Reorganization will provide Safeco High-Yield Bond Fund shareholders with
exposure to substantially the same investment product as they currently have.


     Pioneer and Symetra will pay all of out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer High Yield Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer High Yield
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 Pioneer High Yield Fund and
its shareholders.

distributed.

                                 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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have a higher expenses
per share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Investment strategies    In managing the portfolio and selecting               Pioneer considers both broad economic and

                           to buy the bond back at a stated price or the       factors that are expected to influence
                           Fund's right to require the issuer to buy the       economic activity and interest rates. These

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
market value of fixed income securities tends to be more volatile the longer
the maturity of such security. Since Pioneer Bond Fund may invest in securities
of longer maturity than your Safeco Fund, an investment in Pioneer Bond Fund
may have correspondingly greater risk. 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 debt securities in the Fund's
     portfolio to decline.

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

   o A downturn in equity markets causes the price of convertible securities to
     drop even when the prices of below investment grade bonds otherwise would
     not go down.

   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.


                                       44


     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 (FHLB), 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 the Funds 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.


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.


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.

     Pioneer Bond Fund's Investor Class shares will not be outstanding prior to
the closing of the Reorganization and consequently have no performance history.
However, the performance record of the Investor Class would be modestly higher
than the performance of Class A, B and C shares due to the lower expenses
applicable to the Investor Class.


     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Bond Fund through the Reorganization. In addition, shareholders of
     your Safeco Fund who own shares in their own name (i.e., not in the name of
     a broker or other intermediary) and maintain such account as of the closing
     of the 59Reorganization may purchase Class A shares of Pioneer Bond Fund or
     of any fund in the Pioneer family of funds through such account in the
     future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Intermediate-Term Bond Fund for certain Fund operating expenses (but not
     all of the operating expenses of the Fund) that exceeded the rate of 0.40%
     per annum of the Fund's average daily net assets. This arrangement included
     all fund operating expenses except management fees, Rule 12b-1 fees,
     brokerage commissions, interest, and extraordinary expenses. In 2003, SAM
     began voluntarily reimbursing the Fund to the extent that its total
     expenses exceeded the rate of 0.99% per annum of the Fund's average daily
     net assets for Class A shares, 1.74% per annum for Class B and Class C
     shares, and 0.74% per annum for Investor Class shares. The above table
     reflects "contractual" expense reimbursements from SAM, if any, but does
     not reflect "voluntary" expense reimbursements by SAM.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Bond Fund
     to 0.74% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after five years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

                                       48



(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

     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, (e) the expense limitations are in effect five years Safeco
Intermediate-Term Bond Fund and two years for Pioneer Bond Fund and (f) and the
Investor Class shares of Pioneer Bond Fund convert to Class A shares after two
years. 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 Safeco Intermediate-Term Bond Fund. The Trustees considered the
following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2,
2004, was acquired by Symetra. Symetra informed the Trustees that it did not
intend to continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the investment performance of Pioneer Bond Fund, which has
outperformed your Safeco Fund over the most recent one, five and ten year
periods. For the one, five and ten year periods ended June 30, 2004, Class A
shares of Pioneer Bond Fund had an average annual return of 2.98%, 6.70% and
6.72%, respectively, compared to an average annual return of the Class A shares
and Investor Class shares of 3.66% and 0.02% (one year), 4.86% and 5.86% (five
years) and 5.24% and 5.88% (ten years), respectively, during the same period.
In addition, the Trustees considered the track record of Pioneer in managing
equity and fixed income mutual funds.


                                       49



     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
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 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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 Bond Fund's lower gross expenses and Pioneer's commitment
until the second anniversary of the Reorganization to limit the expenses
(excluding extraordinary expenses) of the Investor Class of Pioneer Bond Fund
to 0.74 % of average daily net assets. The gross expense ratio of Pioneer Bond
Fund's Class A shares is lower than the gross expense ratio of each class of
shares of your Safeco Fund. In addition, the net expense ratio of the Investor
Class of Pioneer Bond Fund is lower than the net expenses of the Class A, Class
B and Class C shares of your Safeco Fund and the same as the net expenses of
the Investor Class. Although you will experience higher expenses once the
Investor Class shares convert to Class A shares after two years, your expenses
will remain the same until the second anniversary of the Reorganization.


     Fifth, the substantially larger size of Pioneer Bond Fund offers greater
opportunity for diversification of the investment portfolio, which should help
to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Trustees also considered the differences in the investment
policies of the two Funds, particularly Pioneer Bond Fund's ability to invest
in securities with longer maturities than your Safeco Fund. While this may
result in Pioneer Bond Fund having greater volatility of net asset value than
your Safeco Fund, the Trustees believe that the factors in favor of the
Reorganization mitigate this risk.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer Bond Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Bond 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 Pioneer Bond Fund and its
shareholders.

     It is impossible to predict how many shares of Pioneer Bond Fund will
actually be received and distributed by your Safeco Fund on the Reorganization
date. The table should not be relied upon to determine the amount of Pioneer
Bond 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer Bond Fund, including its
Independent Trustees, approved the Reorganization. They also determined that
the Reorganization is in the best interests of Pioneer Bond Fund.

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

               Safeco Intermediate-Term Municipal Bond Fund and
                         Pioneer Tax Free Income Fund

                                 PROPOSAL 1(d)


               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 Agreement and
Plan of Reorganization attached as EXHIBIT A-1 because they contain details that
are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco 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
market value of a fixed income security tends to be more volatile the longer
the maturity of such security. Since Pioneer Tax Free Income Fund can invest in
securities of longer maturity than your Safeco Fund, an investment in Pioneer
Tax Free Income Fund may have correspondingly greater 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 debt securities in the Fund's
     portfolio 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 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 Fund's investment 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 Funds' tax-exempt
securities are generally exempt from regular federal income 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 whether an
alternative minimum tax applies to you and about state and local taxes on Fund
distributions.

                                       60



     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.


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)  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 Aggregate Bond Index, an unmanaged measure of
     approximately 15,000 municipal bonds with a minimum credit rating of BBB,
     and that were a part of at least a $50 million issuance made within the
     past fives years and have a maturity of at least two years, is for
     reference only and does not mirror the Fund's investments.

     Pioneer Tax Free Income Fund's Investor Class shares will not be
outstanding prior to the closing of the Reorganization and consequently have no
performance history. However, the performance record of the Investor Class
would be modestly higher than the performance of Class A shares due to the
lower expenses applicable to the Investor Class shares.

     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.

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 your Safeco Fund, the expenses of your
Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer Tax
Free Income Fund, the expenses of Pioneer Tax Free Income Fund for the period
ended December 31, 2003. Future expenses for all share classes may be greater
or less.

- ----------
(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Tax Free Income Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer Tax Free Income Fund or of any fund in the Pioneer family of
     funds through such account in the future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Intermediate-Term Municipal Bond Fund for certain operating expenses (but
     not all of the operating expenses of the Fund) that exceeded the rate of
     0.40% per annum of the Fund's average daily net assets. This arrangement
     included all Fund operating expenses except management fees, Rule 12b-1
     fees, brokerage commissions, interest, and extraordinary expenses. In 2003,
     SAM began voluntarily reimbursing the Fund to the extent that its total
     expenses exceeded the rate of 0.85% per annum of the Fund's average daily
     net assets for Class A shares, 1.60% per annum for Class B and Class C
     shares, and 0.70% per annum for Investor Class shares. The above table
     reflects "contractual" expense reimbursements from SAM, if any, but does
     not reflect "voluntary" expense reimbursements by SAM.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Tax Free
     Income Fund to 0.70% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.

(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after five years from purchase, and the Class B shares
     convert to Class A shares at that time.

(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.


(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit


                                       64



     the expenses attributable to Investor Class shares, Pioneer is not required
     to limit the expenses attributable to Class A shares. Class A shares do not
     currently have an expense limitation and may be subject to higher total
     operating expenses.

     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, (e) the expense limitations are in effect for five years for
Safeco Intermediate-Term Municipal Bond Fund and two years for Pioneer Tax Free
Income Fund and (f) and the Investor Class shares of Pioneer Tax Free Income
Fund convert to Class A shares after two years. 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 Safeco Intermediate-Term Municipal Bond Fund. The Trustees
considered the following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Fund until August 2, 2004, was
acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the historical investment performance of Pioneer Tax Free Income
Safeco Fund and your Safeco Fund are comparable. For the one, five and ten year
periods ended June 30, 2004, Class A shares of Pioneer Tax Free Income Fund had
an average annual return of 1.55%, 4.84% and 5.53%, respectively, compared to
an average annual return of the Class A shares and Investor Class shares of
- -3.82% and -0.27% (one year), 4.13% and 4.94% (five years) and 4.84% and 5.25%
(ten years), respectively, during the same period. In addition, the Trustees
considered the track record of Pioneer in managing equity and fixed income
mutual funds.


                                       65



     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
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 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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 Tax Free Income Fund's lower operating expenses and
Pioneer's commitment until the second anniversary of the Reorganization to
limit the expenses (excluding extraordinary expenses) of the Investor Class of
Pioneer Tax Free Income Fund to 0.70% of average daily net assets. The
estimated expenses of the Investor Class shares of Pioneer Tax Free Income Fund
are below both the gross expenses and expenses net of expense reimbursement of
each class of shares of your Safeco Fund. Although you will experience higher
expenses once the Investor Class shares convert to Class A shares after two
years, your expenses will remain the same until the second anniversary of the
Reorganization.

     Fifth, the substantially larger size of Pioneer Tax Free Income Fund
offers greater opportunity for diversification of the investment portfolio,
which should help to reduce risks.

     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Trustees also considered the differences in the investment
policies of the two Funds, particularly Pioneer Tax Free Income Fund's ability
to invest in securities with longer maturities than your Safeco Fund. While
this may result in Pioneer Tax Free Income Fund having greater volatility of
net asset value than your Safeco Fund, the Trustees believe that the factors in
favor of the Reorganization mitigate this risk.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer Tax Free Income Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer Tax Free
Income 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 Pioneer
Tax Free Income Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Tax Free Income
Fund will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the
amount of Pioneer Tax Free Income 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer Tax Free Income Fund, including its
Independent Trustees, approved the Reorganization. They also determined that
the Reorganization is in the best interests of Pioneer Tax Free Income Fund.

     The Trustees recommend that the shareholders of your Safeco 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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds


     While each Fund has a similar investment objective, primary investment
policies and strategies, there are differences which affect the risk of each
Fund. The market value of fixed income securities tends to be more volatile the
greater the maturity of the security. Pioneer America Income Trust can invest
in securities of greater average maturity than your Safeco Fund and
consequently may have greater risk. However, your Safeco Fund may invest in
U.S. government securities that are not backed by the full faith and credit of
the U.S. Treasury, and consequently have an element of credit risk that is not
present in Pioneer America Income Trust. Generally, however, 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 debt securities in the
          Fund's portfolio to decline

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

     To the extent the Fund invests significantly in mortgage-backed
securities, its exposure to prepayment and extension risks may be greater than
other investments in fixed income securities.

     Although mortgage pools issued by U.S. agencies are guaranteed with
respect to payments of principal and interest, such guarantee does not apply to
losses resulting from declines in the market value of such securities.

                                       75



     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.


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.

     Pioneer America Income Trust's Investor Class shares will not be
outstanding prior to the closing of the Reorganization and consequently have no
performance history. However, the performance record of the Investor Class
would be modestly higher than the performance of Class A shares due to the
lower expenses applicable to the Investor Class.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer America Income Trust through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer America Income Trust or of any fund in the Pioneer family of
     funds through such account in the future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Intermediate-Term U.S. Government Bond Fund for certain Fund operating
     expenses (but not all of the operating expenses of the Fund) that exceeded
     the rate of 0.40% per annum of the Fund's average daily net assets. This
     arrangement included all Fund operating expenses except management fees,
     Rule 12b-1 fees, brokerage commissions, interest, and extraordinary
     expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent
     that its total expenses exceeded the rate of 0.99% per annum of the Fund's
     average daily net assets for Class A shares, 1.74% per annum for Class B
     and Class C shares, and 0.74% per annum for Investor Class shares. The
     above table reflects "contractual" expense reimbursements from SAM, if any,
     but does not reflect "voluntary" expense reimbursements by SAM.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer America
     Income Trust to 0.74% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.

(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after five years from purchase, and the Class B shares
     convert to Class A shares at that time.

(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

                                       79



(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

     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, (e) the expense limitations are in effect for five years for
Safeco Intermediate-Term U.S. Government Fund and two years for Pioneer America
Income Trust and (f) and the Investor Class shares of Pioneer America Income
Trust convert to Class A shares after two years. The examples are for
comparison purposes only and are not a representation of either Fund's actual
expenses or returns, either past or future.

    COMPARISON OF DELAWARE STATUTORY TRUST AND MASSACHUSETTS BUSINESS TRUST


Characteristics of Safeco Intermediate-Term U.S. Government Trust (a series of
a Delaware statutory trust)

  o GOVERNANCE AND MANAGEMENT. Safeco Intermediate-Term U.S. Government Fund
    is a series of the Safeco Taxable Bond Trust, a Delaware statutory trust.
    The governing instrument of Safeco Taxable Bond Trust is its Trust
    Instrument (the "Trust Instrument"). The Trustees of the Safeco Taxable
    Bond Trust are responsible for the management and supervision of Safeco
    Intermediate-Term U.S. Government Fund.

  o SHARE CAPITAL AND CLASSES. The Trust Instrument of Safeco Taxable Bond
    Trust permits the Trustees to issue an unlimited number of full and
    fractional shares of beneficial interest of Safeco Intermediate-Term U.S.
    Government Fund without par value. As of the date of this Proxy
    Statement/Prospectus, the Trustees have authorized shares of Safeco
    Intermediate-Term U.S. Government Fund and have authorized the issuance of
    four classes of shares of Safeco Intermediate-Term U.S. Government Fund,
    designated as Class A, Class B, Class C and Investor Class shares. The
    shares of each class of Safeco Intermediate-Term U.S. Government Fund
    represent an equal proportionate interest in the aggregate net assets
    attributable to that class of the Fund. Holders of each class of shares
    have certain exclusive voting rights on matters relating to their
    respective distribution plans. The different classes of Safeco
    Intermediate-Term U.S. Government Fund may bear different expenses
    relating to the cost of holding shareholder meetings necessitated by the
    exclusive voting rights of any class of shares. In the event of
    liquidation, shareholders of each class are entitled to share pro rata in
    the net assets of their Fund available for distribution to these
    shareholders. Shares of each class entitle their holders to one vote per
    share, are freely transferable and have no preemptive, subscription or
    conversion rights.

  o MEETINGS. Under Delaware law, Safeco Taxable Bond Trust is not required to
    hold annual shareholder meetings for any Fund. Unless otherwise required
    by the Investment Company Act, the Fund has no intention of holding annual
    meetings of shareholders. Pursuant to the Trust Instrument, shareholders
    have power to vote only on certain matters, including (a) the election and
    removal of Trustees; (b) approval of any investment management agreement;
    (c) termination of the Safeco Taxable Bond Trust; (d) certain amendments
    to the Trust Instrument; and (e) such additional matters relating to the
    Trust as may be required by law or as the Trustees may consider desirable.


  o LIABILITY OF SHAREHOLDERS. Delaware law affords shareholders of a Delaware
    statutory trust with the same protections afforded stockholders of a
    Delaware corporation, which means shareholders are not generally subject
    to liability for the debts or obligations of the statutory trust unless
    the entity's trust instrument provides otherwise. The Trust Instrument of
    the Safeco Taxable Bond Trust contains an express disclaimer of
    shareholder liability for acts, obligations or affairs of Safeco
    Intermediate-Term U.S. Government Fund and provides for indemnification
    out of the Fund's assets for all losses and expenses of any shareholder
    held personally liable for reason of being or having been a shareholder.


Characteristics of Pioneer America Income Trust (a Massachusetts business
trust)


  o GOVERNANCE AND MANAGEMENT. Pioneer America Income Trust is a Massachusetts
    business trust. The governing instrument of Pioneer America Income Trust
    is its Agreement and Declaration of Trust ("Declaration of Trust"). The
    business of Pioneer America Income Trust is managed under the direction of
    its Board of Trustees. The Trustees, in addition to viewing the actions of
    the Pioneer America Income Trust's investment adviser, decide upon matters
    of general policy at their regular meetings. The officers of Pioneer
    America Income Trust supervise its business operations.

  o SHARES AND CLASSES. Pioneer America Income Trust is authorized to issue
    shares of beneficial interest and to increase or decrease the aggregate
    number of shares of beneficial interest or the number of shares of any
    class that the Fund has authority to issue. Each share is entitled to one
    vote on all questions relating to the Fund, and each share is entitled to
    participate equally in dividends and capital gains distributions and in
    the residual assets of the respective class in the event of liquidation.

  o MEETINGS. Under Massachusetts law, Pioneer America Income Trust, as a
    registered open-end investment company, is not required to hold annual
    shareholder meetings. Unless otherwise required by the Investment Company
    Act, the Pioneer America Income Trust has no intention of holding annual
    meetings of shareholders. Pursuant to the Declaration of Trust, special
    meetings of shareholders may be called at any time by the Chairman,
    President or by the Board of Trustees or by the secretary upon the written
    request of shareholders entitled to cast at least 25% of the votes
    entitled to be cast at such meeting, provided that such request shall
    state the purposes of such meeting and the matters proposed to be acted
    on.

  o LIABILITY OF SHAREHOLDERS. Shareholders of a Massachusetts business trust
    may, under certain circumstances, be held personally liable for the
    obligations of the trust. However, the Declaration of Trust contains an
    express disclaimer of shareholder liability for acts or obligations of the
    Pioneer America Income Trust or any series of the Pioneer America Income
    Trust and provides


                                       81



    that notice of such disclaimer may be given in each agreement, obligation
    or instrument entered into or executed by the Pioneer America Income Trust
    or its Trustees. Moreover, the Declaration of Trust provides for the
    indemnification out of Pioneer America Income Trust property of any
    shareholders held personally liable for any obligations of the Pioneer
    America Income Trust or any series of the Pioneer America Income Trust.
    The Declaration of Trust also provides that the Pioneer America Income
    Trust shall, upon request, assume the defense of any claim made against
    any shareholder for any act or obligation of the Pioneer America Income
    Trust and satisfy any judgment thereon. Thus, the risk of a shareholder
    incurring financial loss beyond his or her investment because of
    shareholder liability would be limited to circumstances in which the fund
    itself will be unable to meet its obligations. In light of the nature of
    the Pioneer America Income Trust's business and the nature and amount of
    its assets, the possibility of the Pioneer America Income Trust's
    liabilities exceeding its assets, and therefore a shareholder's risk of
    personal liability, is remote.


Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Intermediate-Term U.S. Government Fund. The Trustees
considered the following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2,
2004, was acquired by Symetra. Symetra informed the Trustees that it did not
intend to continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the performance of Pioneer America Income Trust is generally
consistent with the historical investment performance of your Safeco Fund. For
the one, five and ten year periods ended June 30, 2004, Class A shares of
Pioneer America Income Trust had an average annual return of -0.37%, 5.64%, and
5.97%, respectively, compared to an average annual return of the Class A shares
and Investor Class shares of -4.56% and -0.73% (one year), 4.73% and 5.73% (five
years) and 5.79% and 6.29% (ten years), 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 June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
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 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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 lower operating expenses and
Pioneer's commitment until the second anniversary of the Reorganization to
limit the expenses (excluding extraordinary expenses) of the Investor Class of
Pioneer America Income Trust to 0.74% of average daily net assets. The
estimated expenses of the Investor Class of Pioneer America Income Trust are
below both the gross expenses and expenses net of contractual expense
reimbursement of the end class of shares of your Safeco Fund. Although you will
experience higher expenses once the Investor Class shares convert to Class A
shares after two years, based upon the Class A expense ratio of Pioneer America
Income Trust for the most recent fiscal year, Pioneer America Income Trust's
expenses were lower than the gross and net expense ratio of each class of
shares of your Safeco Fund. While there are some differences between the
policies of the two Funds, the Trustees believe that the two Funds represent
substantially equivalent investments.


     Fifth, the substantially larger size of Pioneer America Income Trust
offers greater opportunity for diversification of the investment portfolio,
which should help to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer America Income Trust
received in the Reorganization will provide Safeco Intermediate-Term U.S.
Government Fund shareholders with exposure to substantially the same investment
product as they currently have.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the

                                       82


Reorganizations; (2) the fees and expenses of any proxy solicitation firm
retained in connection with the Reorganizations; (3) the legal fees and
expenses incurred by the Safeco Funds in connection with the Reorganizations;
and (4) the Trustee fees and out of pocket expenses incurred as a result of the
Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer America Income Trust also considered that
the Reorganization presents an excellent opportunity for the Pioneer America
Income Trust 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 Pioneer
America Income Trust and its shareholders.

     The following table sets forth the capitalization of each Fund, and the pro
forma combined Fund as of June 30, 2004.

     It is impossible to predict how many shares of Pioneer America Income
Trust will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the
amount of Pioneer America Income Trust'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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer America Income Trust, including its
Independent Trustees, approved the Reorganization. They also determined that
the Reorganization is in the best interests of Pioneer America Income Trust.

     The Trustees recommend that the shareholders of your Safeco 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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco 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.
Even though the Funds seek to maintain a $1 share price, you could lose money
on your investment or the Fund could fail to generate high current income 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 investment adviser's judgment about the credit quality,
          attractiveness or relative value of a particular security proves to be
          incorrect

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

     o    Inadequate financial information

     o    Smaller, less liquid and more volatile markets

     o    Political and economic upheavals


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.


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 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.

     Pioneer Cash Reserves Fund's Investor Class shares will not be outstanding
prior to the closing of the Reorganization and consequently have no performance
history. However, the performance record of the Investor Class would be
modestly higher than the performance of Class A, B and C shares due to the
lower expenses applicable to the Investor Class.

is attached as Exhibit D.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Cash Reserves Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer Cash Reserves Fund or of any fund in the Pioneer family of funds
     through such account in the future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco Money
     Market Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.30% per annum
     of the Fund's average daily net assets. This arrangement included all Fund
     operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Cash
     Reserves Fund to 0.71% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.

(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  A contingent deferred sales charge may apply if you redeem Class B shares
     of your Safeco Fund that were purchased by exchange from another fund.

(7)  A 1.00% contingent deferred sales charge may apply if, within the first
     twelve months of the initial purchase, you redeem Class C shares that were
     purchased by exchange from another fund

(8)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation and may be subject to higher total operating expenses.

     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, (e) the expense limitations are in effect for five years for
Safeco Money Market Fund and two years for Pioneer Cash Reserves Fund and (f)
and the Investor Class shares of Pioneer Cash Reserves Fund convert to Class A
shares after two years. 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 Safeco Money Market Fund. The Trustees considered the following
matters, among others, in approving the proposal.


     First, SAM, the investment adviser to the Safeco Fund until August 2,
2004, was acquired by Symetra. Symetra informed the Trustees that it did not
intend to continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the investment performance of Pioneer Cash Reserves Fund is
comparable to the historical investment performance of your Safeco Fund. For
the one, five and ten year periods ended June 30, 2004, Class A shares of
Pioneer Cash Reserves Fund had an average annual return of 0.12%, 2.50%, and
3.60%, respectively, compared to an average annual return of the Class A shares
and Investor Class shares of 0.42% and 0.51% (one year), 2.82% and 2.86% (five
years), and 3.82% and 3.85% (ten years) 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 June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 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 June 30, 2004,

                                       94



assets under management of UniCredito Italiano S.p.A. were approximately $151
billion worldwide. Shareholders of your Safeco Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholders account options. The Pioneer
family of mutual funds offers over 62 funds, including domestic and
international equity and fixed income funds and a money market fund that will
be available to your Safeco 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's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Cash Reserves Fund to 0.71% of average daily net
assets. Although you will experience higher expenses once the Investor Class
shares convert to Class A shares after two years, your expenses will remain the
same until the second anniversary of the Reorganization.


     Fifth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.


     Sixth, the Investor Class shares of Pioneer Cash Reserves Fund received in
the Reorganization will provide Safeco Money Market Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer Cash Reserves Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer Cash
Reserves 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 Pioneer
Cash Reserves Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Cash Reserves Fund
will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the
amount of Pioneer Cash Reserves 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer Cash Reserves Fund, including its
Independent Trustees, approved the Reorganization. They also determined that
the Reorganization is in the best interests of Pioneer Cash Reserves Fund.

     The Trustees recommend that the shareholders of your Safeco 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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

 Investment objective      Each Fund seeks to provide as high a level of current interest income exempt from federal
                           income tax as is consistent with the relative stability of capital.

                           The investment objective of each Fund is fundamental and cannot be changed without
                           shareholder approval.

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 or the Fund could fail to generate high current income 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

                                      105



     o    The investment adviser's judgment about the credit quality,
          attractiveness or relative value of a particular security proves to be
          incorrect

     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

     Investing in mutual fund shares is not the same as making a bank deposit.
Your investment is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. You could lose money by investing
in either Fund.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Municipal Bond Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer Municipal Bond Fund or of any fund in the Pioneer family of
     funds through such account in the future without paying this sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Municipal Bond Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.40% per annum
     of the Fund's average daily net assets. This arrangement included all fund
     operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Municipal
     Bond Fund to 0.62% of average daily net assets.


(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.


(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

     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, (e) the expense limitations are in effect for five years for
Safeco Municipal Bond Fund and two years for Pioneer Municipal Bond Fund and
(f) and the Investor Class shares of Pioneer Municipal Bond Fund convert to
Class A shares after two years. 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 Safeco Municipal Bond Fund. The Trustees considered the following
matters, among others, in approving the proposal.


     First, SAM, the investment adviser to the Fund until August 2, 2004, was
acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the significant experience and resources of Pioneer in managing
portfolios of tax exempt securities. At September 30, 2004, Pioneer Managed
Portfolio of tax exempt securities with total assets of approximately $ 1.5
billion.


     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups

                                      109



in Italy, providing investment management and financial services to mutual
funds, institutional and other clients. As of June 30, 2004, assets under
management of UniCredito Italiano S.p.A. were approximately $151 billion
worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your Safeco 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's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Municipal Bond Fund to 0.62% of average daily net
assets. This expense ratio is lower than both the gross expenses and expenses
net of expense reimbursement of the Class A shares. Although you will experience
higher expenses once the Investor Class shares convert to Class A shares after
two years, your expenses will remain the same until the second anniversary of
the Reorganization.

     Fifth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.


     Sixth, the Investor Class shares of Pioneer Municipal Bond Fund received
in the Reorganization will provide Safeco Municipal Bond Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer Municipal Bond Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer Municipal
Bond 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 Pioneer
Municipal Bond Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Municipal Bond Fund
will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the
amount of Pioneer Municipal Bond 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer Municipal Bond Fund, including its
Independent Trustees, approved the Reorganization. They also determined that
the Reorganization is in the best interests of Pioneer Municipal Bond Fund.

                                 PROPOSAL 1(h)


               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 they
contain details that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor
Class shares, Pioneer is not required to limit the expenses attributable to
Class A shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco 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.
Even though each Fund seeks to maintain a $1 share price, you could lose money
on your investment or either Fund could fail to generate high current income
if:

                                      120


     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 investment adviser's judgment about the credit quality,
          attractiveness or relative value of a particular security proves to be
          incorrect

- ----------
(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Tax Free Money Market Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer Tax Free Money Market Fund or of any fund in the Pioneer family
     of funds through such account in the future without paying this sales
     charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Tax-Free Money Market Fund for certain Fund operating expenses (but not all
     of the operating expenses of the Fund) that exceeded the rate of 0.30% per
     annum of the Fund's average daily net assets. This arrangement included all
     Fund operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses. In 2003, SAM began
     voluntarily reimbursing the Fund to the extent that its total expenses
     exceeded the rate of 0.65% per annum of the Fund's average daily net assets
     for the Investor Class shares. The above table reflects "contractual"
     expense reimbursements from SAM, if any, but does not reflect "voluntary"
     expense reimbursements by SAM.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Tax Free
     Money Market Fund to 0.65% of average daily net assets.


(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

     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, (e) the expense limitations are in effect for five years for
Safeco Tax-Free Money Market Fund and two years for Pioneer Tax Free Money
Market Fund and (f) and the Investor Class shares of Pioneer Tax Free Money
Market Fund convert to Class A shares after two years. 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 Safeco Tax-Free Money Market Fund. The Trustees considered the
following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2,
2004, was acquired by Symetra. Symetra informed the Trustees that it did not
intend to continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over
62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
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 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco 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 has experience in managing many other money market and tax
free portfolios. At September 30, 2004, Pioneer managed portfolios investing in
tax exempt securities with aggregate assets of $1.5 billion and money market
portfolios with assets of $531 million.

     Fourth, Pioneer and its affiliates have greater potential for increasing
the size of your Safeco Fund due to Pioneer's experience in distributing mutual
funds through a broader range of distribution channels than currently available
to your Safeco Fund. Over the long-term, if this potential for a larger asset
base is realized, it is expected to increase the portfolio management options
available to the Fund.

     Fifth, Pioneer's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Tax Free Money Market Fund to 0.65% of average daily
net assets. This expense ratio is no higher than both the gross expenses and
expenses net of expense reimbursement of the Investor Class shares of your
Safeco Fund. Although you will experience higher expenses once the Investor
Class shares convert to Class A shares after two years, your expenses will
remain the same until the second anniversary of the Reorganization.

     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account


                                      123


in the future or may exchange those shares for Class A shares of another
Pioneer Fund or purchase Class A share of another Pioneer Fund without paying
any sales charge.


     Seventh, the Investor Class shares of Pioneer Tax Free Money Market Fund
received in the Reorganization will provide Safeco Tax-Free Money Market Fund
shareholders with exposure to substantially the same investment product as they
currently have.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustee fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."


     The Board of Trustees of Pioneer Tax Free Money Market Fund also
considered that the Reorganization presents an excellent opportunity for the
Pioneer Tax Free Money Market 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 Pioneer Tax Free Money
Market Fund and its shareholders.

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

     It is impossible to predict how many shares of Pioneer Tax Free Money
Market Fund will actually be received and distributed by your Safeco Fund on
the Reorganization date. The table should not be relied upon to determine the
amount of Pioneer Tax Free Money Market 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 Safeco Fund.
Similarly, the Board of Trustees of Pioneer Tax Free Money Market Fund,
including its Independent Trustees, approved the Reorganization. They also
determined that the Reorganization is in the best interests of Pioneer Tax Free
Money Market Fund.

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

              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 December 10, 2004, unless your Safeco Fund and the corresponding
          Pioneer Fund agree in writing to a later date. Your Safeco Fund will
          transfer all of its assets to the corresponding Pioneer Fund. The
          corresponding Pioneer Fund will assume your Safeco Fund's liabilities
          that are included in the calculation of your Safeco 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 corresponding Pioneer Fund will issue to the corresponding Safeco
          Fund Investor Class shares with an aggregate net asset value equal to
          the net assets attributable to the corresponding Safeco Fund's shares.
          These shares will immediately be distributed to your Safeco Fund's
          shareholders in proportion to the relative net asset value of their
          holdings of your Safeco Fund's shares on the Closing Date. As a
          result, each Safeco Fund's shareholders will end up as Investor Class
          shareholders of the corresponding Pioneer Fund.


     o    After the distribution of shares, your Safeco 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 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 Safeco 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 Pioneer
Fund to consummate each Reorganization is subject to the satisfaction of
certain conditions, including your Safeco Fund's performance of all of its
obligations under the Plan, the receipt of certain documents and financial
statements from your Safeco Fund and the receipt of all consents, orders and
permits necessary to consummate the Reorganization (see Sections 7 and 8 of the
Plan).

     The obligations of both Funds are subject to the approval of the Plan by
the necessary vote of the outstanding shares of your Safeco Fund, in accordance
with the provisions of your Trust's 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 federal income tax consequences of
each Reorganization. (See Section 8.5 of the Plan).

     Termination of Agreement. The Board of either a Safeco Trust or the
corresponding Pioneer Fund may terminate the Plan (even if the shareholders of
your Safeco Fund have already approved it) at any time before the
Reorganization Date, if that Board believes in good faith that proceeding with
the Reorganization would no longer be in the best interests of shareholders.

                       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 Safeco Fund upon (1) the
          transfer of all of its assets to the Pioneer Fund as described in this
          Proxy Statement /Prospectus or (2) the distribution by your Safeco
          Fund of Pioneer Fund shares to your Safeco Fund's shareholders;


     o    No gain or loss will be recognized by the Pioneer Fund upon the
          receipt of your Safeco Fund's assets solely in exchange for the
          issuance of Pioneer Fund shares to your Safeco Fund and the assumption
          of your Safeco Fund's liabilities by the corresponding Pioneer Fund;

                                      125


     o    The basis of the assets of your Safeco Fund acquired by the
          corresponding Pioneer Fund will be the same as the basis of those
          assets in the hands of your Safeco Fund immediately before the
          transfer;

     o    The tax holding period of the assets of your Safeco Fund in the hands
          of the corresponding Pioneer Fund will include your Safeco Fund's tax
          holding period for those assets;

     o    You will not recognize gain or loss upon the exchange of your shares
          of your Safeco 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
          Safeco Fund surrendered in 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 Safeco Fund
          surrendered in the exchange, provided that you held the shares of your
          Safeco 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 Safeco 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 Reorganization, including the applicability of any state, local or
foreign tax laws.


                                      126



                              PROPOSALS 2(a)-(h)

        APPROVAL OF INTERIM INVESTMENT ADVISORY AGREEMENT WITH PIONEER


Background


     Having determined to recommend the Reorganizations, the Trustees appointed
Pioneer as investment adviser to each Safeco Fund commencing August 2, 2004,
until the closing of the Reorganizations given that Symetra had indicated that
it did not wish to continue to offer investment advisory services to the Safeco
Funds.

Interim Investment Advisory Agreement

     Under the Investment Company Act, shareholders must approve any new
investment advisory agreement for the Funds. However, Rule 15a-4 under the
Investment Company Act permits your Trustees to appoint an adviser on an
interim basis without prior shareholder approval if the new adviser agrees to
provide such services on the same terms as the previous adviser and approves
the investment advisory agreement with that adviser. An adviser may manage on
such an interim basis for a period 150 days. Because Pioneer will be making the
payment to Symetra discussed under "Background to the Reorganizations," any
fees that Pioneer would be entitled to under the interim investment advisory
agreement will be held in escrow by the Fund until shareholder approval of the
agreement is obtained. If shareholders of a Safeco Fund do not approve the
interim investment advisory agreement, Pioneer will not receive the fee under
the current investment advisory agreement with SAM but instead will be paid a
fee based upon Pioneer's cost in managing the Fund. During this period prior to
the meeting, the Funds will be managed as separate Fund and will not be
combined with a Pioneer Fund. During this period, you also will not be able to
exchange your shares in a Fund for shares of a Pioneer Fund. If the appointment
of Pioneer as interim investment adviser is not approved by December 30, 2004,
Pioneer will no longer provide advisory services to the Funds, unless an
extension of the 150 day period is permitted by a rule or independent position
of the staff of the SEC.

     Reasons for Approving the Interim Investment Advisory Agreement and
Board's Recommendation

     The Trustees recommend that the shareholders of the Safeco Funds approve
the interim investment advisory agreements. In determining to appoint Pioneer
as investment adviser on an interim basis, the Trustees considered many of the
same factors on which the recommendation to approve the Reorganizations are
based. These factors include:

     o    SAM, the investment adviser to the Safeco Funds until August 2, 2004,
          was acquired by Symetra. Symetra informed the Trustees that it was not
          interested in continuing to provide investment advisory services to
          the Safeco Funds. Consequently, a change in your Safeco Fund's
          investment adviser was necessary.

     o    The resources of Pioneer. At June 30, 2004, Pioneer managed over 62
          investment companies and accounts with approximately $35 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, institutions, and other clients. As of June 30, 2004,
          assets under management of UniCredito Italiano S.p.A. were
          approximately $151 billion worldwide.

     o    The track record of Pioneer in managing other investment companies
          with similar strategies.

     o    Pioneer's willingness to proceed with the Reorganization and to limit
          expenses of the Portfolios as discussed above.

     o    Pioneer's investment process, style and philosophy with respect to
          equity and fixed income investing.

     o    Pioneer's willingness to act as investment adviser to each of the
          Funds.


     o    Pioneer's investment process, style and philosophy with respect to
          equity and fixed income investing.

     o    The expertise and experience of Kenneth Taubes as portfolio manager of
          several of Pioneer's bond funds and the head of fixed income
          investments at Pioneer.

     o    Pioneer's willingness to act as investment adviser to each of the
          Funds.



Safeco Advisory Agreement


     The following is a summary of the material terms of the Safeco Advisory
Agreement. The Safeco Fund's Advisory Agreement with SAM terminated on August
2, 2004.

     Services. Under the terms of the Safeco Advisory Agreement, SAM managed
the Funds' investments, subject to the supervision of the Board. At its
expense, SAM provided office space and all necessary office facilities,
equipment and personnel for managing the investments of the Funds.


                                      127



     Compensation. As compensation under the Safeco Advisory Agreement, each
Safeco Fund paid SAM a monthly advisory fee at an annual rate as listed in the
below table of the Fund's average daily net assets calculated each business day
and paid monthly, as listed in the table below. In addition, SAM had
contractually agreed to reimburse each Fund to the extent a Fund's total annual
expenses during any of the Fund's fiscal years, exceed 0.40% (0.30% for Safeco
Money Market Fund and Safeco Tax-Free Money Market Fund) of its average daily
net asset value in such year. This arrangement included all Fund operating
expenses except management fees, Rule 12b-1 fees, brokerage commissions,
interest, and extraordinary expenses.

                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,
institutional and other clients. As of June 30, 2004, assets under management
were approximately $150 billion worldwide, including over $35 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 unreliable, a Pioneer Fund may 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.

     To the extent a Pioneer Fund invests in securities of non-U.S. issuers, 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 fund's
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. The Class A shares of the Pioneer Funds you receive in the
Reorganizations will not be subject to any sales charge. Moreover, if you own
shares in your own name as of the closing of the Reorganizations (i.e., not in
the name of a broker or other intermediary) and maintain your account, you may
purchase additional Class A shares of the corresponding Pioneer Fund through
such account in the future or may exchange those shares for Class A shares of
another Pioneer Fund without paying any 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.

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.

     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

                                      131


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.

     If we identify an account that engages in such activity, the fund
     and the distributor reserve the right to refuse or restrict any
     purchase order (including exchanges) for that account and other
     accounts under common ownership or control.
- --------------------------------------------------------------------------------

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

     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. ou may only make up to four exchange redemptions of
$25,000 or more per account per calendar year out of a 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 IRC. While financial intermediaries that
maintain omnibus accounts that


                                      134


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.

     Excessive Trading. The fund discourages excessive and short-term trading
practices, such as market timing, that may disrupt portfolio management
strategies and harm fund performance. 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 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.

     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. We also limit
the number of exchanges of $25,000 or more in any calendar year.

     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. Frequently, fund
shares are held through omnibus accounts maintained by financial intermediaries
such as brokers and retirement plan administrators where the holdings of
multiple 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.

     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 Safeco 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.

     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.

                                      135


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. Distributions from each Pioneer Fund's net short-term
capital gains and dividends from net investment income (other than
exempt-interest dividends, as described below) are taxable as ordinary income.
Since each Pioneer Fund's income is derived primarily from sources that do not
pay "qualified dividend income," taxable dividends from each such fund
generally will not qualify for taxation at the maximum 15% U.S. federal income
tax rate available to individuals on qualified dividend income. For the Pioneer
Tax Free Income Fund, Pioneer Municipal Bond Fund, Pioneer Tax Free Money
Market Fund, and Pioneer California Tax Free Income Fund, dividends from each
such fund's tax-exempt interest, called "exempt-interest dividends," are exempt
from regular federal income tax.


     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 (other than exempt-interest 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' Class A Rule 12b-1 Plans


     As described above, each Pioneer Fund has adopted a Rule 12b-1 plan for
its Class A shares (the "Class A Plans" or the "Plans"). Because the 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.

     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 6, 2003. 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 Anderson LLP. The information for any semi-annual 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 increase in net realized and unrealized gain (loss) on
     investments of $0.02 per share, and the ratio of net investment income to
     average net assets decreased by 0.18%.
(b)  Ratios include the revision of estimate for printing expenses.

(a)  On January 1, 2001, the Trust began accreting discounts and amortizing
     premiums on debt securities. The effect of this change for the year ended
     December 31, 2001, was to decrease net investment income by $0.02 per
     share, increase net realized and unrealized gain (loss) by $0.02 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

     Being present at the Meeting alone does NOT revoke a previously executed
and returned proxy.

     Only shareholders of record on October 8, 2004 (the "record date") are

Other Business


     Your Safeco Fund's Board of Trustees knows of no business to be presented
for consideration at the Meetings other than Proposals 1(a)-(h) and 2(a)-(h).
If other business is properly brought before a Meeting, proxies will be voted
according to the best judgment of the persons named as proxies.


Adjournments


     If, by the time scheduled for a 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 Safeco Fund will set a new record date), your Safeco 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
Safeco Fund may also arrange to have votes recorded by telephone by officers
and employees of your Safeco 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 votes would not be counted at the Meeting. Your Safeco 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.

Internet Voting

     You will also have the opportunity to submit your voting instructions via
the Internet by utilizing a program provided through a vendor. 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/Prospectus 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
          [           ] us at [1-800          ] 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.

Shareholders' Proposals


     Your Safeco 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 Safeco Fund to Safeco Mutual Funds, Attention Legal
Department, 4854 154th Place, N.E., Redmond, WA 98052 within a reasonable time
before any meeting. If the reorganization is completed, your Safeco Fund will
not hold another shareholder meeting.


Appraisal Rights


     If the Reorganization of your Safeco Fund is approved at the Meeting,
shareholders of your Safeco 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 Safeco
Funds, however, have the right to redeem their Fund shares until the closing
date of the Reorganizations. After the Reorganization, shareholders of your
Safeco Funds will hold shares of the Pioneer Funds which may also be redeemed
at net asset value without being subject to deferred sales charges.

     WHEREAS, the Acquiring Fund is authorized to issue shares of beneficial
interest.


     WHEREAS, the Board of Trustees of the Safeco Trust and the Board of
Trustees of the Acquiring Trust have determined that the Reorganization is in
the best interests of the Acquired Fund shareholders and the Acquiring Fund
shareholders, respectively, and is not dilutive of the interests of those
shareholders.


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

     1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR 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, with an aggregate NAV equal
to the NAV of the Acquired Fund, 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

     (b) The Acquired Fund has provided the Acquiring Fund with a list of all

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

Acquired Fund pursuant to Paragraph 1.1 hereof. Each Acquired Fund Shareholder
shall receive such number of Acquiring Fund Shares that have an aggregate NAV
equal to the aggregate NAV of the shares of beneficial interest of the Acquired
Fund (the "Acquired Fund Shares") held of record by such Acquired Fund
Shareholder on the Closing Date. Such liquidation and distribution will be

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

Shareholders. The Safeco 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 for its Investor Class shares. 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 Safeco 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
reports, Tax Returns (as defined in Paragraph 4.1), or other documents with the
Commission, any state securities commissions, and any federal, state or local
tax authorities or any other relevant regulatory authority, is and shall remain
the responsibility of the Safeco Trust.

     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
Acquiring Fund Share shall be computed by Pioneer Investment Management, Inc.
(the "Acquiring Fund Adviser") in the manner set forth in the Acquiring Fund's
Declaration of Trust (the "Declaration"), or By-Laws, and the Acquiring Fund's
then-current prospectus and statement of additional information. The NAV of the
Acquired Fund shall be computed by Safeco Asset Management, 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 Paragraph 5.7 (the "Statement of Assets and
Liabilities"), said assets and liabilities to be valued in the manner set forth
in the Acquired Fund's then current prospectus and statement of additional
information. 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 the 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 Acquiring Fund and the Acquired Fund shall cause the Acquiring
Fund Adviser and the Acquired Fund Administrator, respectively, to deliver a
copy of its valuation report to the other party at Closing. All computations of
value shall be made by the Acquiring Fund Adviser and the Acquired Fund
Administrator in accordance with its regular practice as pricing agent for the
Acquiring Fund and the Acquired Fund, respectively.

     3.   CLOSING AND CLOSING DATE


     3.1 The Closing Date shall be December 8, 2004, 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.


                                      A-2



     3.2 Portfolio securities that are held other than in book-entry form in
the name of State Street Bank and Trust Company (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 Acquiring Fund Shares or 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,
addresses, federal taxpayer identification numbers and backup withholding and
nonresident alien withholding status and certificates of the Acquired Fund
Shareholders and the number and percentage ownership of outstanding Acquired
Fund Shares owned by each Acquired Fund Shareholder as of the Valuation Time,
certified by the President or a Secretary of the Safeco Trust and its
Treasurer, Secretary or other authorized officer (the "Shareholder List") as
being an accurate record of the information (a) provided by the Acquired Fund
Shareholders, (b) provided by the Acquired Fund Custodian, or (c) derived from
the Safeco Trust's records by such officers or one of the Safeco Trust's
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
Closing Date, or provide evidence satisfactory to the Acquired Fund that such
Acquiring Fund Shares have been credited to the Acquired Fund's account on the
books of the Acquiring Fund. At the Closing, each party shall deliver to the
other such bills of sale, checks, assignments, 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 Schedule 4.1 hereto, the Safeco 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 Safeco Trust. The Safeco
     Trust is a statutory trust validly existing and in good standing under the
     laws of the State of Delaware 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 Safeco 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 Safeco 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 Safeco 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 Safeco 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 Safeco
     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
     Safeco Trust nor the Acquired Fund is


                                      A-3



     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 income and changes in NAV, as of and for the
     fiscal year ended December 31, 2003, 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 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 December 31, 2003, 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 June 30, 2004, 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. The Acquired Fund 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 below) that it was required to file, and all such Tax Returns
          were complete and accurate in all respects. The Acquired Fund has not
          been informed by any jurisdiction that the jurisdiction believes that
          the Acquired Fund was required 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;

               (D) All Tax Returns filed by the Acquired Fund constitute
          complete and accurate reports of the respective Tax liabilities and
          all attributes of the Acquired Fund or, in the case of information
          returns and payee statements, the amounts required to be reported, and
          accurately set forth all items required to be included or reflected in
          such returns;

               (E) The Acquired Fund has not waived or extended any applicable
          statute of limitations relating to the assessment or collection of
          Taxes;

               (F) The Acquired Fund has not been notified that any examinations
          of the Tax Returns of the Acquired Fund are currently in progress or
          threatened, and no deficiencies have been asserted or assessed against
          the Acquired Fund as a result of any audit


                                      A-4



          by the Internal Revenue Service or any state, local or foreign taxing
          authority, and, to its knowledge, no such deficiency has been proposed
          or threatened;

               (G) The Acquired Fund has no actual or potential liability for
          any Tax obligation of any taxpayer other than itself. The Acquired
          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 Acquired Fund is not a party to
          any Tax allocation, sharing, or indemnification agreement;

               (H) The unpaid Taxes of the Acquired Fund for tax periods through
          the Closing Date do not exceed the accruals and reserves for Taxes
          (excluding accruals and reserves for deferred Taxes established to
          reflect timing 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 required by law to withhold or collect have been duly withheld or
          collected and, to the extent required, have been timely paid to the
          proper governmental agency;

               (I) The Acquired Fund has delivered to the Acquiring Fund or made
          available to the Acquiring Fund complete and accurate copies of all
          Tax Returns of the Acquired Fund, together with all related
          examination reports and statements of deficiency for all periods not
          closed under the applicable statutes of limitations and complete and
          correct copies of all private letter rulings, 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 Acquired 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 disposition made on or
          prior to the Closing Date; or (iv) prepaid amount received on or prior
          to the Closing Date;

               (K) The Acquired Fund has not taken or agreed to take any action,
          and is not aware of any agreement, plan or other circumstance, that is
          inconsistent with the representations set forth in Annex B;

               (L) There are (and as of immediately following the Closing there
          will be) no liens on the assets of the Acquired Fund relating to or
          attributable to Taxes, except for Taxes not yet due and payable;

               (M) The Tax bases of the assets of the Acquired Fund are
          accurately reflected on the Acquired Fund's Tax books and records;

               (N) The Acquired Fund has not incurred (or been allocated) an
          "overall foreign loss" as defined in Section 904(f)(2) of the Code
          which has not been previously recaptured in full as provided in
          Sections 904(f)(2) and/or 904(f)(3) of the Code;

               (O) The Acquired Fund is not a party to a gain recognition
          agreement under Section 367 of the Code;

               (P) The Acquired Fund does not own any interest in an entity that
          is 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, except
          as set forth on Schedule 4.1; and

               (R) For purposes of this Agreement, "Taxes" or "Tax" shall mean
          all taxes, charges, fees, levies or other similar assessments or
          liabilities, including without limitation income, gross receipts, ad
          valorem, premium, value-added, excise, real property, personal
          property, sales, use, transfer, withholding, employment, unemployment,

          customs, duties, franchise and other taxes imposed by the United
          States of America or any state, local or foreign government, or any
          agency thereof, or other political subdivision of the United States or
          any such government,


                                      A-5



          and any interest, fines, penalties, assessments or additions to tax
          resulting from, attributable to or incurred in connection with any tax
          or any contest or dispute thereof; and "Tax Returns" shall mean all
          reports, returns, declarations, statements or other information
          required to be supplied to a governmental or regulatory authority or
          agency, or to any other person, in connection with Taxes and any
          associated schedules or work papers produced in connection with such
          items;

          (i) All issued and outstanding Acquired Fund Shares are, and at the
     Closing Date will be, duly and validly issued and outstanding, fully paid
     and nonassessable by the Acquired Fund. All of the issued and outstanding
     Acquired Fund Shares will, at the time of Closing, be held of record by the
     persons and in the amounts set forth in the Shareholder List submitted to
     the Acquiring Fund pursuant to Paragraph 3.5 hereof. The Acquired Fund does
     not have outstanding any options, warrants or other rights to subscribe for
     or purchase any Acquired Fund Shares, nor is there outstanding any security
     convertible into any Acquired Fund Shares;

          (j) At the Closing Date, the Acquired Fund will have good and
     marketable title to the Acquired Assets, and full right, power and
     authority to sell, assign, transfer and deliver the Acquired Assets to the
     Acquiring Fund, and, upon delivery and payment for the Acquired Assets, the
     Acquiring Fund will acquire good and marketable title thereto, subject to
     no restrictions on the full transfer thereof, except such restrictions as
     might arise under the Securities Act;

          (k) The Safeco 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 Safeco Trust's Board of Trustees, and,
     subject to the approval of the Acquired Fund's shareholders, assuming due
     authorization, execution and delivery by the Acquiring Fund, this Agreement
     will constitute a valid and binding obligation of the Acquired 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;

          (l)The information to be furnished by the Acquired Fund to the
     Acquiring Fund for use in applications for orders, registration statements,
     proxy materials and other documents which may be necessary in connection
     with the transactions contemplated hereby and any information necessary to
     compute the total return of the Acquired Fund shall be accurate and
     complete and shall comply in all material respects with federal securities
     and other laws and regulations applicable thereto;

          (m) The information included in the proxy statement (the "Proxy
     Statement") forming part of the Acquiring Fund's Registration Statement on
     Form N-14 filed in connection with this Agreement (the "Registration
     Statement") that has been furnished in writing by the Acquired Fund to the
     Acquiring Fund for inclusion in the Registration Statement, on the
     effective date of that Registration Statement and on the Closing Date, will
     conform in all material respects to the applicable requirements of the

     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading;

          (n) Upon the effectiveness of the Registration Statement, no consent,
     approval, authorization or order of any court or governmental authority is
     required for the consummation by the Safeco Trust or the Acquired Fund of
     the transactions contemplated by this Agreement;

          (o) All of the issued and outstanding Acquired Fund Shares have been
     offered for sale and sold in conformity with all applicable federal and
     state securities laws, except as may have been previously disclosed in
     writing to the Acquiring Fund;

          (p) The prospectus and statement of additional information of the
     Acquired Fund and any amendments or supplements thereto, furnished to the
     Acquiring Fund, did not as of their dates or the dates of their
     distribution to the public contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     to make the statements therein, in light of the circumstances in which such
     statements were made, not misleading;

          (q) The Acquired Fund currently complies in all material respects
     with, and since its organization has complied in all material respects
     with, the requirements of, and the rules and regulations under, the
     Investment Company Act, the Securities Act, the Exchange Act, state "Blue
     Sky" laws and all other applicable federal and state laws or regulations.
     The Acquired Fund currently complies in all material respects with, and
     since its organization has complied in all material respects with, all
     investment objectives, policies, guidelines and restrictions and any

     4.2 Except as set forth on Schedule 4.2 hereto, 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 Fund is a series of the Acquiring Trust. The
     Acquiring Trust is a [statutory][business] trust duly organized, validly
     existing and in good standing under the laws of the [State of
     Delaware][Commonwealth of Massachusetts]. 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;

          (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


                                      A-7



     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 [most recent fiscal year end] 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) Since [most recent fiscal year end], except as specifically
     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 [ ], there has not been any material adverse
     change in the Acquiring Fund's financial condition, assets, liabilities,
     business or prospects, or any incurrence by the Acquiring 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 (h) (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;

          (i) (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;

               (D) All Tax Returns filed by the Acquiring Fund constitute
          complete and accurate reports of the respective liabilities for Taxes
          and all attributes of the Acquiring Fund or, in the case of
          information returns and payee 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;

               (F) The Acquiring Fund has not been notified that any
          examinations of the Tax Returns of the Acquiring Fund are currently in
          progress or threatened, and no deficiencies have been asserted or
          assessed against the Acquiring Fund as a result of any audit by the
          Internal Revenue Service or any state, local or 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 Safeco Trust or made
          available to Safeco Trust complete and accurate copies of all Tax
          Returns of the Acquiring Fund, together with all related examination
          reports and statements of deficiency for all periods not closed under
          the applicable statutes of limitations and complete and correct copies
          of all private letter rulings, 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. The Acquiring 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;

               (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 transactions contemplated in this Agreement to undergo)
          a change in its method of accounting resulting in


                                      A-8



          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

          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;

               (J) The Acquiring Fund has not taken or agreed to take any
          action, and 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
          "overall foreign loss" as defined in Section 904(f)(2) of the Code
          which has not been previously recaptured in full as provided in
          Sections 904(f)(2) and/or 904(f)(3) of the Code;

               (L) The Acquiring Fund is not a party to a gain recognition
          agreement under Section 367 of the Code;

          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;

          (j) The Acquiring Fund currently complies, and at all times since its
     organization has complied, in all material respects with the requirements
     of, and the rules and regulations under, the Investment Company Act, the
     Securities Act, the Exchange Act, state "Blue Sky" laws and all other
     applicable federal and state laws or regulations. The Acquiring Fund
     currently complies in all material respects with, and since its
     organization has complied in all material respects with, all investment
     objectives, policies, guidelines and restrictions and any compliance
     procedures established by the Acquiring Trust with respect to the Acquiring
     Fund. All advertising and sales material used by the Acquiring Fund
     complies in all material respects with and has complied in all material
     respects with the applicable requirements of the Securities Act, the
     Investment Company Act, the rules and regulations of the Commission, and,
     to the extent applicable, the Conduct Rules of the NASD and any applicable

     the Commission, the NASD or any state securities authorities by the
     Acquiring Fund have been duly filed and have been approved or declared

     the circumstances in which they were made, not false or misleading;

          (k) 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 an

     The Acquiring Fund Shares to be issued and delivered to the Acquired Fund

                          ON BEHALF OF [SAFECO 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 ,
2004 between [Pioneer Trust], a [Delaware statutory] [Massachusetts business]
trust, on behalf of its series [Pioneer Fund] ("Acquiring Fund"), and [Safeco
Trust], a Delaware statutory trust ("Safeco Trust"), on behalf of its series

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 Investor Class 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 Safeco 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

but not defined herein shall have the meanings ascribed to them in the
Agreement.

     1. Acquired Fund is a series of Safeco Trust, a statutory trust organized
under the laws of the State of Delaware, 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. Pursuant to the transaction, Acquired Fund will transfer to Acquiring
Fund, and Acquiring Fund will acquire, at least 90% of the fair market value of

foregoing, any amounts Acquired Fund uses to pay its transaction expenses and
to make redemptions and distributions immediately before the transaction
(except (a) redemptions in the ordinary course of its business required by
section 22(e) of the Investment Company Act and (b) regular, normal dividend
distributions made to conform to its policy of distributing all or
substantially all of its income and gains to avoid the obligation to pay
federal income tax and/or the excise tax under Section 4982 of the Code) will
be included as assets it held immediately before the transaction.

     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.


                                      A-18



     7. As of the Closing Date, the adjusted basis and fair market value of the
Acquired Assets will equal or exceed the Assumed Liabilities 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. All of the assets held by Acquired Fund as
of the opening of business on August 2, 2004 (the date the Acquiring Fund
Adviser became investment adviser to Acquired Fund) were Acquired Fund's
historic business assets within the meaning of Treasury Regulation Section
1.368-1(d)(3) (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 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.

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).

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.

shares, if any) in exchange for the Acquired Assets and the assumption of the
Assumed Liabilities shall be determined by Pioneer Investment Management, Inc.
(the "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

     4.   REPRESENTATIONS AND WARRANTIES

     4.1 Except as set forth on Schedule 4.1 hereto, the Safeco 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 Safeco Trust. The Safeco
     Trust is a statutory trust validly existing and in good standing under the
     laws of the State of Delaware 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 Safeco 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 Safeco 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 Safeco 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 Safeco 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 Safeco
     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
     Safeco 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;

                                      A-23


          (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 income and changes in NAV, as of and for the
     fiscal year ended December 31, 2003 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 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 December 31, 2003, 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 June 30, 2004, 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 below) that it was required to file, and all such Tax Returns
          were complete and accurate in all respects. The Acquired Fund has not
          been informed by any jurisdiction that the jurisdiction believes that
          the Acquired Fund was required 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;

               (D) All Tax Returns filed by the Acquired Fund constitute
          complete and accurate reports of the respective Tax liabilities and
          all attributes of the Acquired Fund or, in the case of information
          returns and payee statements, the amounts required to be reported, and
          accurately set forth all items required to be included or reflected in
          such returns;

               (E) The Acquired Fund has not waived or extended any applicable
          statute of limitations relating to the assessment or collection of
          Taxes;

               (F) The Acquired Fund has not been notified that any examinations
          of the Tax Returns of the Acquired Fund are currently in progress or
          threatened, and no deficiencies have been asserted or assessed against
          the Acquired Fund as a result of any audit by the Internal Revenue
          Service or any state, local or foreign taxing authority, and, to its
          knowledge, no such deficiency has been proposed or threatened;


               (G) The Acquired Fund has no actual or potential liability for
          any Tax obligation of any taxpayer other than itself. The Acquired
          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 Acquired Fund is not a party to
          any Tax allocation, sharing, or indemnification agreement;


                                      A-24



               (H) The unpaid Taxes of the Acquired Fund for tax periods through
          the Closing Date do not exceed the accruals and reserves for Taxes
          (excluding accruals and reserves for deferred Taxes established to
          reflect timing 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 required by law to withhold or collect have been duly withheld or
          collected and, to the extent required, have been timely paid to the
          proper governmental agency;


               (I) The Acquired Fund has delivered to the Acquiring Fund or made
          available to the Acquiring Fund complete and accurate copies of all
          Tax Returns of the Acquired Fund, together with all related
          examination reports and statements of deficiency for all periods not
          closed under the applicable statutes of limitations and complete and
          correct copies of all private letter rulings, 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 Acquired 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 disposition made on or
          prior to the Closing Date; or (iv) prepaid amount received on or prior
          to the Closing Date;


               (K) The Acquired Fund has not taken or agreed to take any action,
          and is not aware of any agreement, plan or other circumstance, that is
          inconsistent with the representations set forth in Annex B;


               (L) There are (and as of immediately following the Closing there
          will be) no liens on the assets of the Acquired Fund relating to or
          attributable to Taxes, except for Taxes not yet due and payable;

               (M) The Tax bases of the assets of the Acquired Fund are
          accurately reflected on the Acquired Fund's Tax books and records;

               (N) The Acquired Fund has not incurred (or been allocated) an
          "overall foreign loss" as defined in Section 904(f)(2) of the Code
          which has not been previously recaptured in full as provided in
          Sections 904(f)(2) and/or 904(f)(3) of the Code;

               (O) The Acquired Fund is not a party to a gain recognition
          agreement under Section 367 of the Code;

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

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

Acquiring Fund will not furnish any consideration


                                      A-34



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.

                       TAX REPRESENTATION CERTIFICATE OF

                                [SAFECO TRUST]
                          ON BEHALF OF [SAFECO 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
_______________________ , 2004 between [Pioneer Trust], a [Delaware statutory]
[Massachusetts business] trust, on behalf of its series [Pioneer Fund]
("Acquiring Fund"), and [Safeco Trust], a Delaware statutory trust ("Safeco
Trust"), on behalf of its series [Safeco 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
Investor Class 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 Safeco 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 Safeco Trust, a statutory trust organized
under the laws of the State of Delaware, 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 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.


                                      A-36



     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 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. All of the assets of the Acquired Fund
held by Acquiring Fund as of the opening of business on August 2, 2004 (the
date the Acquiring Fund Adviser became the investment adviser to Acquired Fund)
were Acquired Fund's historic business assets within the meaning of Treasury
Regulation Section 1.368-1(d)(3) (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

                 Exhibit B -- Form of Interim Advisory Agreement


     AGREEMENT dated as of August 2, 2004, between Pioneer Investment
Management, Inc. ("Pioneer"), a Delaware corporation and a member of the
UniCreditio Italiano Banking Group, Register of Banking Groups, and [SAFECO
TRUST], a Delaware statutory trust (the "Trust"), on behalf of its series
[SAFECO FUNDS] (the "Fund").


     Whereas, Safeco Asset Management Company has acted as investment adviser to
the Fund pursuant to an Investment Advisory Agreement dated (the "Prior
Agreement").


     Whereas, the Prior Agreement has been approved by the Board of Trustees of
the Trust and the shareholders of the Fund.

     Whereas, the Prior Agreement is being terminated as a result of
assignment.

     Whereas, the Board of Trustees has determined to appoint Pioneer as
investment adviser to the Fund.

     Whereas, this Agreement is being entered into in reliance upon Rule 15a-4
under the Investment Company Act of 1940, as amended (the "Investment Company
Act").

     Now therefore the Trust and Pioneer agree as follow:

     Section 1. The Trust appoints Pioneer as investment adviser of the Funds
for the period and on the terms set forth herein. Pioneer accepts such
appointment.

     Section 2. Pioneer and the Trust, on behalf of the Fund, hereby agree that
the provisions of the Prior Agreement (other than as to the term of the Prior
Agreement, the identity of the Adviser and the use of the "Safeco" name) are
incorporated herein by reference and made a part hereof as if references to the
Adviser were to Pioneer. Without limiting the forgoing, Pioneer shall be
entitled to the fee for its services provided for in the Prior Agreement from
(but exclusive of) the date hereof until the termination of this Agreement,
except as provided in Section 3 below.

     Section 3. In the event that this Agreement is not approved by a majority
of the Trust's outstanding voting securities (as such term is used in the
Investment Company Act), Pioneer shall be entitled to a fee equal to the cost
to Pioneer of performing its services under this Agreement in lieu of the fee
provided for in Section 2. For purposes of this Agreement, Pioneer's costs in
providing the services under this Agreement shall be equal to the pro rata
portion of Pioneer's expenses for the term of this Agreement attributable to
its investment company advisory business, calculated as follows: Pioneer cost
in providing investment advisory services to its investment companies of the
same type (i.e., domestic equity, international, fixed income, money market)
multiplied by a fraction the numerator of which shall be the average daily net
assets of the Fund during the term of this Agreement and the denominator of
which shall be the average month end net assets under Pioneer's management of
all of its investment company clients.

     Section 4. The compensation earned by Pioneer under Section 2 of this
Agreement shall be held in an interest bearing escrow account with the Fund's
custodian. If a majority of the outstanding voting securities approves this
Agreement prior to the end of its term, the amount in the escrow account
(including any interest earned) shall be paid to Pioneer. If a majority of the
outstanding voting securities do not approve this Agreement prior to the end of
its term, Pioneer shall be entitled to be paid, out of the escrow account the
lesser of (i) the amount in the escrow account (including any interest earned
on that amount while in escrow) and (ii) the fee provided for in Section 3
(plus any interest on that amount while in escrow), with any remaining amount
in the escrow account being returned to the Fund.

     Section 5. This Agreement shall become effective on August 2, 2004. Unless
terminated as provided below, this Agreement shall remain in full force and
effect until the earliest of (i) the closing of the reorganization of the Fund
into [name of Pioneer Fund], (ii) approval of a Management Contract between the
Fund and Pioneer and (iii) a date that is the later of 150 days after the date
of the termination of the Prior Agreement or such later date as may be
consistent with a rule or interpretive position (formal or informal) of the
staff of the Securities and Exchange Commission. This Agreement may be
terminated at any time without payment of penalty by vote of the Trustees of
the Trust or by vote of a majority of the outstanding voting securities of the
Fund. Pioneer may terminate this Agreement at any time without payment of any
penalty on not less than 60 days written notice to the Fund. This Agreement
shall automatically terminate upon its assignment as defined in the Investment
Company Act.

                                      B-1



In witness whereof, the parties hereto have executed this Agreement as the 2nd
day of August 2004.

            Exhibit C -- 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 Exchange Act, 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.

     In circumstances where two or more broker-dealers offer comparable prices
and executions, preference may be given to a broker-dealer which has sold
shares of a fund as well as shares of other investment companies managed by
Pioneer. This policy does not imply a commitment to execute all portfolio
transactions through all broker-dealers that sell shares of the fund.

     None of the funds used any brokers affiliated with Pioneer during its most
recently completed fiscal year in connection with its portfolio transactions.

           Exhibit D -- Portfolio Manager's Discussion of Performance

Report From the Fund Managers
Safeco California Tax-Free Income Fund
As of June 30, 2004

How did the Fund perform?

     Though it posted an overall negative return, the Safeco California
Tax-Free Income Fund outperformed its benchmark index, the Lehman Brothers Long
Municipal Bond Index, for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     After a first quarter market rally, then sell-off, the first half ended
with long-term bond yields rising about 50 basis points during the second
quarter. The impetus for this change was more news demonstrating a stronger
economy and an increasing threat of renewed inflation, which in turn could
inspire the Federal Reserve to increase short-term yields at a faster pace than
expected. With a longer average maturity than most of its peers, the Fund
performed relatively poorly as bond prices declined sharply.

What changes did you make to the Fund and why?

     Transactions for the period included two small sales of Los Angeles DWAP
4.25 '34 to retail customers at aggressive prices, and a tax swap. We sold San
Jose Airport 5 '32 and bought Orange County Sanitary District 5 '33 in order to
realize a small loss, which can be used to offset gains for tax purposes.

Report From the Fund Managers
Safeco High-Yield Bond Fund
As of June 30, 2004

How did the Fund perform?

     Year-to-date performance of the fund has exceeded both the benchmark, the
Merrill Lynch High-Yield Master II Index, and the high-yield peer median.

What Factors impacted the Fund's performance?

     Our credit selection and overweight in CCC-rated bonds largely accounted
for the Fund's good relative performance during the first half of the year. We
likely removed the overweight in CCC too soon and missed the rally during the
last part of the second quarter.

     Nine of our holdings announced refinancing and/or tenders, which provided
a positive "pop" to returns reflecting our credit picks. Two negative credit
events were Pegasus Satellite, which deteriorated quickly, and in MCI stock we
received in exchange for WorldCom bonds. The latter declined as short-term
bankruptcy investors sold the stock and long-term holders have been slow to add
positions in a difficult sector.

What changes did you make to the Fund and why?

     The number of overall holdings has been reduced to a more manageable
level, between 100 and 120 positions. Diversification remained strong as we
trimmed larger holdings and selectively added to several top-25 positions. No
bond exceeds 2% of assets and we continue to reduce the percentage of our asset
level in the top 10.

     We continue to overweight industrial and cyclical sectors, underweight
defensive sectors and BB-rated credits, and maintain a shorter duration versus
our benchmark. Our overall yield-to-maturity and coupon return to shareholders
are close to or exceed the benchmark. We achieve this by holding high coupon
"cushion" bonds likely to be called in the near term.

     High-yield bonds, especially those rated BB, will be hurt as Treasury
rates rise at this point in the cycle. The effort to counteract rising interest
rates is three-fold. First, underweighting BB-rated issues and slightly shorten
the duration. Second, adding adjustable rate bonds to offset the Federal
Reserve rate increases. Finally, identifying near-term credit upgrade
candidates not fully reflected in the market. The latter is admittedly
difficult in this fairly valued market.

Report From the Fund Managers
Safeco Intermediate-Term Bond Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Intermediate-Term Bond Fund slightly outperformed its benchmark
index, the Lehman Aggregate Bond Index, for the six-month period ending June
30, 2004.

What factors impacted the Fund's performance?

     While interest rates declined in the first quarter, they rose sharply
during the second. The Fund benefited its relatively short duration and 10.5%
underweight holdings in Treasury securities, which underperformed the most of
any sector. However, the fund was hurt by its 6.4% underweight in mortgage
securities, the best-performing sector of the second quarter.

     The Federal Reserve increased the Fed Funds rate to 1.25% from 1.00% on
June 30; the first rate change in a year. We believe that the Fed will continue
to raise rates through year-end and into 2005, most likely in 25 basis points
steps. The Fed appears to be focused on inflation and employment so we expect
the bond market will be very sensitive to both data releases. Any unanticipated
strength or weakness in either could cause yields to gyrate in either direction
although we believe the overall trend should be up. In this scenario the Fund,
with its shorter duration versus the peer group, should perform well.

What changes did you make to the Fund and why?

     Early in the year we restructured the maturity profile of our Treasury
exposure, laddering holdings across the entire yield curve and selecting
specific positions with the highest yield per unit of duration risk. We also
increased our exposure to callable agency securities to increase the
portfolio's yield; this helped cushion the blow from the second quarter's rise
in rates.

     Second quarter activity was aimed at maintaining our slightly short
duration and maintaining the mortgage-backed securities (MBS) allocation. The
Fund used the cash from mortgage paydowns to purchase mortgage pass-through to
maintain the allocation of MBS helping to maintain the portfolio's yield. The
Fund reduced its exposure in the corporate bond sector modestly, swapping a
30-year corporate bond for a similar maturity Treasury bond. The Fund also
tendered some 10-year corporate bonds and invested the proceeds in similar
maturity Corporates.

Report From the Fund Managers
Safeco Intermediate-Term Municipal Bond Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Intermediate-Term Municipal Bond Fund matched its benchmark
index, the Lehman Brothers 7-Year Municipal Bond Index, for the six-month
period ending June 30, 2004.

What factors impacted the Fund's performance?

     After gaining fairly steadily since last summer, bond prices moved down
during most of the first quarter, recovering somewhat in late May and June. We
underperformed during the period. The steep decline (approximately 100 basis
point in a two-month period beginning in March and ending in May) hurt us, and
the period of increased stability at the end of the quarter was not long enough
for us to recover from the hit.

What changes did you make to the Fund and why?

     We did not make any changes in the basic structure of the fund. We did
just one trade during each quarter. During the first quarter, we added to our
position in Chicago, IL Tax Increment 5%. During the second quarter, we
purchased Columbus, Ohio, general obligation bonds. These are very high
credit-quality bonds from a state where a significant premium is usually paid
by investors in order to gain the state tax exemption. The bonds, however, were
sold at close to general market values. We believe that at some point in the
future, the spread will widen out and their value will increase relative to
other bonds.

Report From the Fund Managers
Safeco Intermediate-Term U.S. Government Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Intermediate-Term U.S. Government Fund outperformed its
benchmark index, the Lehman Intermediate Government Index, for the six-month
period ending June 30, 2004.

What factors impacted the Fund's performance?

     Rising interest rates marked a performance shift between the first and
second quarters. While rates fell in the first quarter, favoring longer
duration securities, rates began an upward climb in the second. The Fund's
shorter duration, along with its exposure to mortgage-backed securities (MBS),
allowed it to benefit from this rising interest-rate environment and
contributed to improved performance relative to the benchmark for the first six
months of the year.

What changes did you make to the Fund and why?

     Trading activity for the first six months was aimed at modestly
lengthening the Fund's duration, increasing yield, and maintaining the MBS
allocation.

     During the first half of the year, we sold a four-plus year Treasury to
buy a longer duration Treasury security (2023 maturity) to increase the Fund's
exposure to the long end of the yield curve and lengthen its duration. Some of
the proceeds were also used to buy 30-year 5.5% FNMA pass-throughs to maintain
the allocation of MBS slightly above 40%.

     The Fund used the cash from mortgage pay downs to purchase a 30-year 5.0%
FNMA pass-through to maintain the allocation of MBS slightly above 40%. The
Fund also sold an eight-year Treasury and bought a 10-year Federal Home Loan
Bank (FHLB) bond. The FHLB bond yielded almost 1.5% more than the Treasury.
This added both yield and duration to the portfolio.

Report From the Fund Managers
Safeco Money Market Fund
As of June 30, 2004

How did the Fund Perform?

     The Fund had returns for the six-month period ending June 30, 2004 above
the average of other taxable money market funds. However, the 12-month return
on the Fund was lower than the 3.2% year-over-year increase in the Consumer
Price Index (CPI) as of the end of June 2004.

What factors impacted the Fund's performance?

     After a full year of the Federal Funds target rate of 1.00%, the Federal
Reserve's Open Market Committee (FOMC) finally raised the rate to 1.25% on June
30. The Fed Funds futures market anticipates a 0.25% rise in the rate at each
of the four remaining FOMC meetings in 2004 and even higher rates in 2005.

     The main reason the Fund outperformed the Lipper benchmark was the large
holdings (33%) of 7-day reset floating rate notes that reset off of the 1-month
London inter-bank offer rate (LIBOR). LIBOR-based securities currently offer
higher rates than other available money market securities, and the frequent
rate reset of the notes captures higher rates more quickly in a rapidly rising
rate environment. Also contributing to the superior returns were the Fund's
holdings of longer-term corporate bonds purchased at relatively high yields on
a steep money market yield curve.

What changes did you make to the Fund and why?

     We increased the allocation of floating rate notes. This has become our
asset class of choice because the spread is much higher than commercial paper.
We continued to reduce our holdings of Commercial paper (to 31% of Fund)
relative to our peers (49% according to iMoneyNet). Commercial paper remains
one of the lowest-yielding assets in the prime money markets.

     After rates had risen significantly, we made a purchase of a Federal Home
Loan Bank (FHLB) thirteen-month maturity bond which is callable every three
months and some purchases of one-year bank and broker paper.

Report From the Fund Managers
Safeco Municipal Bond Fund
As of June 30, 2004

How did the Fund perform?

     Though it had negative overall performance, the Safeco Municipal Bond Fund
outperformed its benchmark Index, the Lehman Long Municipal Bond Index, for the
six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     After a typical first quarter, long-term bond yields rose about 50 basis
points during the second quarter. This was due to more news demonstrating a
stronger economy and an increasing threat of renewed inflation, both of which
could inspire the Federal Reserve to increase short-term yields at a faster
pace than expected.

     With a longer average maturity than most of its peers, the Fund performed
relatively poorly during the first half, as bond prices declined sharply.

What changes did you make to the Fund and why?

     Three new issues were purchased during the first half of 2004. All were
rated A by Standard & Poor's, and offered significant additional yield to the
benchmark AAA scale. In the first quarter, we purchased $4 million of
Dorchester County School District 5.25 12/1/29 to yield 4.90%. These A-rated
bonds provided 55 basis points more yield than AAA bonds, a very attractive
spread.

     In the second quarter, Empire State Development Authority 5.125 7/1/21
came to market at a yield of 4.70%, 49 basis points more than AAA bonds. Puerto
Rico Highway 5.125% 7/1/43 bonds were offered at a yield of 5.20%, which was an
additional 42 basis points over AAA-rated bonds.

     We also swapped out of several bonds priced near par into deeper
discounts. This move afforded a greater total return in the event of a market
turnaround without adding significant downside potential.

Report From the Fund Managers
Safeco Tax-Free Money Market Fund
As of June 30, 2004

How did the Fund perform?

     The Fund had returns above the average of other tax-free money market
funds for the six-month period ending June 30, 2004.

What factors impacted the fund's performance?

     Although in absolute numbers the return is small, the fund has continued
to fare well compared to its peers. The structure of the portfolio serves us
well.

     As of June 30, 66% of the fund was invested in variable rate demand option
(VRDO) bonds which can be tendered on a daily or weekly basis, and 34% in
six-month and one-year put bonds. The heavy weighting in VRDOs gives us
liquidity and flexibility, along with a competitive yield. The longer put bonds
let us lock in some higher rates on a smaller portion of the fund.

What changes did you make to the fund and why?

     We have not made any significant changes to the fund. The barbell strategy
outlined above -- with a heavy concentration in VRDOs, a smaller concentration
in put bonds, and not much in between -- has worked for us consistently.

Portfolio Management's Discussion of Fund Performance (as of April 30, 2004)

High-yield bonds continued a string of solid performance during the six months
ended April 30, 2004. Here, Fund manager Margaret Patel explains the rebound in
the high-yield market and the factors that influenced the Fund's performance.

Q: How did the Fund perform?

A: During the six months ended April 30, 2004, the Fund had a total return
   based on net asset value of 4.43% for the Fund's Class A shares, 4.01% for
   Class B shares, 4.07% for Class C shares, 4.65% for Class R shares, and
   4.61% for Class Y shares. To compare, the Merrill Lynch High Yield Master
   II Index returned 5.35%.

Q: What was the environment like for the high-yield market during the past six
   months?

A: The yield spread, or differential, between high-yield bonds and comparable
   Treasuries narrowed, highlighting the solid performance of the high-yield
   market. This yield spread narrowing reflected a brighter outlook for the
   economy and the declining default rate among high-yield bonds. The Federal
   Reserve Board aided the positive backdrop by providing ample liquidity to
   the markets in the form of historically low interest rates. A modest level
   of new supply also benefited the high-yield market, helping to buoy price
   appreciation among outstanding bonds as demand for the asset class remained
   high. With interest rates so low, investors looked to the high-yield market
   for more attractive yields at a time when the strengthening economy made
   them more comfortable venturing there.

Q: Why did the Fund modestly under perform the Merrill Lynch High Yield Master
   II Index?

A: Much of the stronger relative performance offered by the index came from the
   out-performance of low-quality bonds rated CCC or lower. We had very little
   exposure to the lower-rated segments of the market, instead focusing more
   of the Fund on those securities rated BB or BBB. These higher-rated bonds
   tend to be more sensitive to changes in interest rates and, thus, suffered
   on a relative basis as yields on comparable intermediate Treasury
   securities rose during the period. However, we felt that the better-quality
   issues should offer more favorable performance at this juncture in the
   market cycle. In addition, more speculative industries, such as airlines,
   telecommunications and lower-tier electric utilities, were among the best
   performers during the period. We avoided these industries, feeling that
   they were too risky and did not meet our investment criteria, particularly
   because we believed that they were less likely to benefit from an economic
   upturn than the alternatives we found in other sectors.

Q: What was your strategy during the period?

A: We decreased the proportion of the Fund devoted to convertible securities
   from about 56% of the portfolio to just over 49%, and increased its stake
   in standard corporate high-yield bonds from about 43% to about 50%. We made
   this move because many convertible securities became fully valued, having
   benefited from low interest rates and the substantial increase in the
   underlying value of the issuing companies' stocks. We invested the proceeds
   from these sales in the areas we judged to be most attractively valued
   within the high-yield market. We also reduced the Fund's allocations to the
   technology and health care sectors, including investments in pharmaceutical
   and biotechnology companies. These securities offered substantial
   out-performance, reaching fully valued levels. In addition, some technology
   companies called a number of convertible bonds. That is, the issuers
   decided to redeem the bonds by paying them off, requiring us to surrender
   the securities. The assets we gained from our sales and redemptions were
   used to increase the Fund's focus on cyclical companies that we felt were
   best positioned to benefit from an improving economy. Overall, these firms
   should benefit from better supply and demand fundamentals, as well as being
   helped modestly by the cheapening U.S. dollar.

Q: Does your recent strategy mean you're gravitating away from a focus on
   convertible securities?

A: No, it does not. Convertible securities remain a viable investment
   alternative for the Fund. When we use them, we look for those convertibles
   that are selling at discounted prices and offering high yields. We invest
   in companies within industries where generic high yield bonds are not in
   strong supply, especially smaller companies within rapidly growing
   industries. Discounted convertible securities can offer appealing prospects
   because their prices can appreciate more than regular bonds if the
   underlying value of the company's stock rises. Also, holders of convertible
   bonds can earn attractive yields similar to those offered within the
   high-yield market.

                                      D-18


Q: Which investments proved to be some of the top performers during the fiscal
   year? Which disappointed?

A: Tesoro Petroleum was one of the top performers during the period. This West
   Coast refining company profited from improved refining margins. Wabash
   National, which manufactures truck trailers, benefited from improved demand
   and better pricing. The health care sector offered particularly strong
   performance for the Fund, with Protein Design Labs, Enzon Pharmaceuticals,
   Human Genome, Ligand Pharmaceuticals and Sepracor all demonstrating success
   with drug discovery or bringing new pharmaceutical products forward for
   approval. In technology, Flir Systems, Xerox, Conexant Systems, Lam
   Research, Brooks Automation and Triquint Semiconductors all posted improved
   operating results driven by firmer pricing and a better outlook for the
   industry. Disappointments included basic materials holdings Freeport Mac
   MoRan and Inco. These holdings declined due to concerns about softening
   demand for their products from China. In addition, publisher Houghton
   Mifflin fell due to disappointing earnings results and projections.

Q: What is your outlook?

A: We remain optimistic because we expect corporate earnings growth rates to
   continue to come in above long-term averages as the U.S. economy expands.
   We also anticipate further declines in the default rate to well below its
   historical average of 3%, due to solid economic growth and substantial
   liquidity in the marketplace. Although we expect yields on Treasuries to
   rise, we feel that the extra income offered by high-yield bonds should
   outweigh the price erosion that accompanies such an increase. The outlook
   for the equity market is very bright, reflecting positive earnings
   forecasts. As a result, convertible securities could appreciate in price
   should the underlying stocks move upward in response to better earnings
   reports.

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's Discussion of Fund Performance (as of June 30, 2004)

As market interest rates spiked up in the final half of the 12-month period
ending June 30, 2004, high-yield corporate bonds and mortgage-backed securities
provided the best defensive protection, as conditions changed in the U.S.
fixed-income market. In the following discussion, Kenneth J. Taubes discusses
the factors that influenced Pioneer Bond Fund's performance during the 12
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 the 12 months ended June 30, 2004?

A: In a challenging period for fixed-income investing, Pioneer Bond Fund
   outdistanced both market benchmarks and competitive peer group averages.
   For the 12 months, the Fund's Class A shares had a total return of 2.98%,
   while Class B and Class C shares returned 2.04% and 2.11%, respectively,
   all at net asset value. During the same 12 months, the Lehman Aggregate
   Bond Index had a return of 0.32%, while the average return of funds in
   Lipper's A-Rated Corporate Debt category was 0.04%. The Fund also continued
   to deliver a competitive yield. The standardized 30-day SEC yield on Class
   A shares on June 30, for example, was 4.30%.

Q: What were the factors that affected performance?

A: The Fund's performance was helped both by asset allocation and good security
   selection. We had the largest overweight positions in the two asset classes
   with the best performance during the 12 months: high-yield corporate bonds
   and mortgage-backed securities. Throughout the year, we kept the Fund's
   high-yield exposure close to the 20% limit of our policy. That strategy
   helped substantially as the high-yield market, as measured by the Merrill
   Lynch High Yield Master II Index, returned 10.30% for the 12 months. We
   also had more than 40% of assets invested in mortgage securities during a
   period in which mortgages were the best performing part of the
   investment-grade fixed-income market. As a result, typically 60% to 65% of
   Fund assets were invested in the two best performing parts of the bond
   market. Both high-yield bonds and mortgage-backed securities tend to be
   more resistant to the effects of price losses from increasing
   interest-rates than other bonds because of their yield advantages. The
   performance of mortgage-backed securities is also helped by the tendency of
   mortgage prepayment risk to decline as interest rates rise. We held our
   allocation to Treasury securities, the worst performing part of the bond
   market, to less than 10% of assets during the period, and focused our
   Treasury exposure on inflation-protected Treasuries, which outperformed
   standard Treasury securities. Treasuries were the worst performing part of
   the fixed-income market. During the 12-month period, the prices of 10-year
   Treasuries declined by 7.5%.

Q: What types of security selections had the greatest influence on performance?


A: Several high-yield corporate bonds made significant contributions to
   performance. Bonds issued by Corning, which restructured its business to
   focus on the production of the material used for flat screen monitors, did
   very well, as did securities of retailer J.C. Penney, which improved its
   credit position through restructuring and the sale of its pharmacy chain
   division. Bonds issued by hotel chains also did well as the economy
   improved and business travel increased. Among the top performers in the
   portfolio were bonds issued by the Hilton, Starwood and John Q. Hammond
   hotel chains. The securities of insurance company Allmerica Financial also
   appreciated in price during the period as a result of that company's
   positive restructuring efforts.

Q: How would you describe the Fund's overall positioning?

A: We kept the Fund positioned to benefit from the improving economy, which
   helps support the corporate bond market, while guarding against the threat
   of rising interest rates. At the end of the fiscal year, on June 30,
   mortgage securities accounted for 44.9% of Fund assets, while corporate
   high-yield bonds made up 18.5% of the portfolio. About 30.3% of assets were
   in investment-grade corporates, and just 1.4% of assets were invested in
   Treasuries. Because rising interest rates tend to undermine bond prices, we
   shortened the Fund's duration to lower its sensitivity to changes in
   interest rates. Duration, a measure of interest-rate sensitivity, declined
   during the period from 4.7 years at the start of the fiscal year to 4.3
   years on June 30, 2004. Average credit quality on June 30, 2004 was A.

                                      D-21


Q: What is your outlook for the bond market?

A: We believe the economy is healthy and should continue to grow. Short-term
   rates currently are below the rate of inflation and should be expected to
   continue to rise in the coming months. The Federal Reserve began to raise
   the important Fed Funds rate, the most influential short-term rate, on June
   30, and we expect further tightening by the Fed in the months ahead. We
   believe market rates on longer-term bonds, which rose in the months leading
   up to the June 30 announcement, probably are priced appropriately for
   current conditions, but pressure on shorter-term and intermediate-term
   interest rates should continue for several more quarters. The outlook for
   corporate securities appears good, however, as more companies gain
   additional pricing power, which should help them strengthen their balance
   sheets. We recently have initiated some positions in the steel industry,
   for example, an area we have generally avoided in the past. In this
   environment, we anticipate maintaining a focus on corporate bonds and
   mortgage-backed securities and expect to maintain the Fund's position to
   mute the impact of rising interest rates of short- and intermediate-term
   securities by keeping duration relatively short.

Portfolio Management's Discussion of Fund Performance (as of June 30, 2004)

     While yields and prices on municipal bonds fluctuated widely during the
first half of 2004, on June 30, 2004, yields were higher and prices were lower
than they had been six months before. In this environment, the Fund distributed
a relatively high level of tax-free income to shareholders. 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 Safeco Fund.

Q: How did the Fund perform?

A: For the six-month period ended June 30, 2004, Pioneer Tax Free Income Fund's
   Class A shares produced a -1.65% return; Class B shares returned -1.96%;
   and Class C shares -1.96%, all at net asset value. The Fund's benchmark,
   the Lehman Brothers Municipal Bond Index returned -0.68%, and the average
   return of the 302 funds in the Lipper General Municipal Debt Funds Category
   was -0.99%. Lipper is an independent monitor of mutual fund performance.
   While we shortened the duration of the Fund, we did not reduce it so much
   as to sacrifice yield. The funds in the Lipper category have a much shorter
   duration than the Fund; and that difference in duration accounted for the
   underperformance relative to Lipper. (Duration measures a bond's
   sensitivity to interest rate changes. In a rising interest rate
   environment, a shorter duration is usually advantageous because it
   mitigates price erosion.) The Fund's Class A shares generated a 30-day SEC
   tax-free yield of 5.23% as of June 30, 2004. That translates into a taxable
   equivalent yield of 8.05%, based on the maximum federal income-tax rate of
   35%.

Q: Why did the Fund under perform the benchmark?

A: The relative underperformance of the Fund's tobacco bonds, which accounted
   for about 9% of net assets, was the primary detractor from performance
   versus the Lehman Brothers Municipal Bond Index. While tobacco bonds
   provided a very high level of income, their prices declined because certain
   court rulings regarding tobacco companies were interpreted negatively by
   the investment community. The Fund's allocation to transportation bonds,
   which was about 4% of net assets, also detracted from performance. During
   the period, Delta Airlines raised the possibility of filing for bankruptcy.
   While we did not hold Delta bonds, nearly all airline bonds were negatively
   affected by the company's announcement. The Fund's 34.6% allocation to
   AAA-rated bonds also held back total return.

Q: What was the investment environment like during the period?

A: There were two distinct environments during the period. For the first
   quarter of 2004, interest rates continued to decline, because investors
   were not sure about the sustainability of the economic recovery. As we
   moved into the second quarter, however, data began to indicate that the
   economy was on a relatively strong recovery course and that hundreds of
   thousands of new jobs had been created. The strong jobs numbers sparked
   concerns about accelerating inflation and higher interest rates. Against
   this backdrop, yields on both taxable and tax-free bonds rose sharply.
   While yields moved higher across all maturities, those on short-term bonds
   went up the most.

Q: What contributed to performance?

A: The declining interest rates in the first quarter of 2004 were a substantial
   help to performance. Also, the higher-yielding -- or below investment-grade
   -- bonds in the portfolio aided results.

Q: What were the principal strategies used in managing the Fund?

A: In keeping with the Fund's guidelines, we maintained our strategy of keeping
   up to 10% of net assets in below investment-grade securities, which
   enhanced the Fund's income and performance. The rest of the portfolio was
   invested in investment-grade bonds. We focused on economically sensitive
   market sectors, areas in which the underlying credit quality of
   fixed-income securities tends to improve during periods of economic
   recovery. These sectors included the hospital/health care, transportation,
   and power/energy parts of the market. As mentioned above, to moderate the
   Fund's price decline as interest rates rose, we shortened duration.

                                      D-24


Q: What is your outlook?

A: We believe the economy will continue on a positive growth path. The Fed
   boosted rates by 0.25% on June 30, and we expect the central bank to
   continue making modest rate hikes over the second half of 2004. The Fed's
   actions could push short-term yields higher. We believe the possibility of
   higher interest rates will increase the level of income to the Fund. At the
   same time, the portfolio's shorter duration will help guard against the
   possibility of price loss as interest rates begin to rise. Another factor
   that could benefit the Fund is the significant decline in the issuance of
   new bonds. In 2003, low interest rates made it attractive for
   municipalities to borrow money in record numbers. In 2004, new issuance
   could be down as much as 20%. While supply may be down, demand remains
   constant. This supply/demand dynamic can raise the value of certain
   municipal bonds.

or the factors influencing the Fund's historical or future performance are

market forecasts discussed will be realized.

Portfolio Management's Discussion of Fund Performance (as of June 30, 2004)

In an improving economy, uncertainty about rising interest rates dominated
market sentiment. As a result, the yields on fixed-income securities declined
and then rose, as investors tried to determine when the Federal Reserve would
raise interest rates and by how much. In this volatile environment, Pioneer
America Income Trust delivered a relatively high level of income to
shareholders. 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 six months.

Q: How did the Trust perform during the six-month period ended June 30, 2004?

A: For the six-month period ended June 30, 2004, Class A shares of Pioneer
   America Income Trust produced a total return of -0.14% at net asset value.
   The Trust performed in line with the Lehman Brothers Government Bond Index,
   which returned -0.13% for the same period. It under performed the Lehman
   Brothers Fixed-Rate Mortgage-Backed Index, which returned 0.77%. We
   attribute the Fund's underperformance relative to the Lehman Brothers
   Fixed-Rate Mortgage-Backed Index to the fact that the index has significant
   exposure to securities issued by the Federal Home Loan Mortgage Corporation
   (Freddie Mac) and the Federal National Mortgage Association (Fannie Mae),
   which outperformed. Because these securities do not have the backing of the
   full faith and credit of the U.S. Government, we do not invest in them. The
   Trust outperformed the -0.32% return generated by the General U.S.
   Government Funds Category of Lipper, Inc., an independent monitor of mutual
   fund performance. At the end of the period, the 30-day SEC yield for Class
   A shares was 4.26%.

Q: What was the investment environment like during the period?

A: For the first three months of 2004, concerns about geopolitical issues and
   the "jobless" economic recovery kept interest rates at 45-year lows. When
   we moved into the second calendar quarter of 2004, however, the employment
   picture changed dramatically. Several hundred thousand jobs were added to
   the economy in April and May, leading to concerns about accelerating
   inflation, the pace of Federal Reserve tightening and higher interest
   rates. In this environment, market interest rates rose, causing the yield
   curve to flatten. (The yield curve shows the relationship between bond
   yields and maturity lengths.) Normally, the yield curve is positively
   sloped, with yields on long-term bonds exceeding those on short-term bonds.
   The yield curve flattens when yields on short term bonds rise more than
   those on long-term bonds, as was the case during the period. As interest
   rates rose, bond yields went up and prices declined.

Q: What investment strategies contributed to performance?

A: Nearly 75% of net assets were invested in mortgage-backed 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 GNMA securities outperformed Treasuries, the Trust's focus on
   mortgages relative to the benchmark was the biggest aid to total return. In
   the volatile interest-rate environment, we were concerned about the
   prepayment risk that is associated with mortgage-backed securities. 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 selected mortgages that
   had lower weighted average coupon (stated rate of interest) rates, which we
   believe are less likely to be prepaid.

                                      D-27


Q: What investment strategies detracted from performance?

A: Nearly 25% of the portfolio was invested in Treasury securities with
   predominantly short- and intermediate-term maturities. As yields on
   securities in these maturity ranges moved higher, their prices declined. As
   a result, the Trust's exposure to bonds in the middle of the yield curve
   held back results.

Q: What is your outlook over the next several months?

A: We believe the economy is on a sustained path for improvement and are
   concerned that the seeds for higher inflation are being planted. The
   Federal Reserve raised interest rates by 0.25% on June 30 and is likely to
   continue doing so at a measured pace over the next two years. As interest
   rates move higher, we will consider using a barbell strategy in managing
   the Treasury portion of the Trust -- that is, we may sell some of our
   intermediate-term holdings and add securities in the one-to-two-year range
   and in the 20 plus-year range. With this approach, the Trust should benefit
   from the higher yields that long-term bonds provide and from the relative
   price stability of short-term securities. We will also seek mortgage-backed
   securities that are selling at a discount and that can provide the Trust
   with relatively high yields as well as the potential for price
   appreciation.

or the factors influencing the Trust's historical or future performance are

                             and there can be no guarantee the Fund will be
                             able to maintain a stable net asset value of $1.00
                             per share. An investment in the Fund is not
                             insured or guaranteed by the Federal Deposit
                             Insurance Corporation or any other government
                             agency. 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.

                             Pioneer has agreed to limit the fund's expenses
                             for any class of shares or waive a portion of its
                             management fee to maintain a net asset value of

                             limitation may result in a 0.00% yield for one or
                             more classes of 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

Portfolio Management's Discussion of Fund Performance (as of June 30, 2004)

Short-term interest rates remained at 46-year lows during the first half of
2004, although the U.S. Federal Reserve Board finally signaled a shift in its
accommodative monetary policy on June 30 when it raised the key Fed Funds Rate
from 1.00% to 1.25%. Throughout the six months, Pioneer Cash Reserves Fund
maintained a $1 share price and provided modest current income consistent with
the low 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 leading 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 six months ended June 30, 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 the first half of 2004?

A: For the six months ended June 30, 2004, Pioneer Cash Reserves Fund Class A
   shares had a total return of 0.09%, while Class B, Class C and Class R
   shares each had returns of 0.03%. All returns were at net asset value. For
   the same six months, the average return in Lipper's Money Market Fund
   category was 0.17%. On June 30, 2004, the Fund's seven-day effective yield
   for Class A shares was 0.35%.

Q: What factors affected Fund performance?

A: Short-term interest rates remained at historically low levels over the six
   months. It was a period, however, in which evidence steadily accumulated
   that the U.S. economy was recovering briskly. Growth Domestic Product
   (GDP), for example, grew by an annual rate of 3.9% for the first three
   months. The nation's industrial production increased by 5.6% since June 30,
   2004, and the economy added 1.4 million new jobs during the same 12 months.
   Evidence of the economy's vibrancy became more persuasive during the six
   months, especially after the Department of Labor released an unexpectedly
   strong new-jobs report for March. Market interest rates began rising and
   expectations grew that the Federal Reserve Board finally would shift from
   its accommodative monetary policy and begin raising short-term interest
   rates. The Fed confirmed those expectations on the final day of the six
   month period when it raised the influential Fed Funds Rate by one quarter
   of one percent and signaled that it was likely to raise the rate further in
   subsequent months to head-off inflationary threats.

Q: Given this environment, what strategies did you pursue?

A: We held to our quality orientation in managing the Fund, but gradually
   lowered the effective duration from 61 days on December 31, 2003, to 51
   days by June 30, 2004. We did this as we saw that the Federal Reserve was
   likely to begin to raise rates. A shorter duration portfolio gives the Fund
   more flexibility in investing in new, higher-yielding securities as rates
   start to rise.

Q: What is your investment outlook?

A: We anticipate that while the Federal Reserve will continue to stimulate
   continued economic growth, it is likely to raise short term rates further
   for the remainder of 2004 and at least the beginning of 2005. Given this
   outlook, we expect to keep effective duration relatively short to give us
   the flexibility to capture additional yield as rates rise. However, we also
   expect to take a more bar belled approach, with concentrations both in very
   short, one-to two-month securities and in one-year maturities, where higher
   yields are available. We also intend to consider opportunities to invest in
   floating-rate notes, where we can obtain higher yields without taking more
   risk.

TBA   (To Be Assigned) securities are purchased on a forward commitment basis
      with an approximate (generally plus/minus 2.5%) principal and no definite
      maturity date period. The actual principal amount and maturity date will
      be determined upon settlement.

(a)   No adjustments are shown to the unaudited pro forma combined schedule of
      investments due to the fact that upon consummation of the merger, no
      securities would need to be sold in order for Pioneer America Income Trust
      to comply with its prospectus restrictions. The foregoing sentence shall
      not restrict in any way the ability of the investment adviser of either of
      the funds from buying or selling securities in the normal course of such
      fund's business and operations.

   The accompanying notes are an integral part of these financial statements.

NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
6/30/04
(Unaudited)

1.    General

The accompanying pro forma combined financial statements are presented to show
the effect of the proposed acquisition (the "acquisition") of Safeco
Intermediate-Term U.S. Government Fund by Pioneer America Income Trust.

Under the terms of an Agreement and Plan of Reorganization between the Funds,
the combination of Pioneer America Income Trust and Safeco Intermediate-Term
U.S. Government 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 Safeco Intermediate-Term U.S. Government Fund in exchange
for a new "Investor Class" of shares of Pioneer America Income Trust at net
asset value, which will be established upon consummation of the merger. The
accompanying schedules of investments, statements of assets and liabilities and
the related statements of operations of Pioneer America Income Trust and Safeco
Intermediate-Term U.S. Government Fund have been combined as of and for their
most recent 12 months ended June 30, 2004. Adjustments have been made to
expenses for duplicate services that would not have been incurred if the merger
took place on July 1, 2003. Following the acquisition, Pioneer America Income
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 Pioneer America Income Trust and
Safeco Intermediate-Term U.S. Government Fund included in their respective
semiannual reports to shareowners dated June 30, 2004.

2.    Organization and Significant Accounting Policies

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.

After the merger, the Trust will consist of five classes of shares - Class A,
Class B, Class C, Class R and Investor Class shares. Class R shares were first
publicly offered on April 1, 2003. Investor Class shares are being offered as
part of the acquisition. Shares of Class A, Class B, Class C, Class R and
Investor Class each represent an interest in the same portfolio of investments
of the Trust and have equal rights to voting, redemptions, dividends and
liquidation, 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 Investor Class
shares.

Each Fund's management has prepared their respective financial information using
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the pro forma financial statements, and the reported amounts of income, expenses
and gains and losses on investments during the reporting periods. Actual results
could differ from those estimates.


                                      -10-


The following is a summary of significant accounting policies consistently
followed by the Trust, which are in conformity with those generally accepted in
the investment company industry:

      A.    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 there are no
other readily available valuation method are valued at their fair values as
determined by, or under the direction of the Fund's Board of Trustees. At June
30, 2004, there were no securities fair valued. 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 pay downs. 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.

Gains and losses on sales of investments are calculated on the identified cost
method for both financial reporting and federal income tax purposes.

      B.    Federal Income Taxes

Each fund has previously elected to be taxed as a "regulated investment company"
under the Internal Revenue Code. After the acquisition, it will be 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.

At December 31, 2003, the combined capital loss carryforward of $8,538,000
includes a net capital loss carryforward of $1,398,000 from the merger with
Safeco Intermediate-term U.S. Government Fund, the full use of which may be
limited.

      C.    Fund Shares

The Trust records sales and repurchases of its shares as of trade date. Pioneer
Funds Distributor, Inc. (PFD), the principal underwriter for the Trust and a
wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito
Italiano), earned $40,046 in underwriting commissions on the sale of Trust
shares for the 12 months ended June 30, 2004.

      D.    Class Allocations

Distribution fees are calculated based on the average daily net asset value
attributable to Class A, Class B, Class C, Class R, and Investor Class shares of
the Trust, respectively. Shareowners of each class share all expenses and fees
paid to the transfer agent, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), for its services, which are allocated based on the number of
accounts in each class and the ratable allocation of related out-of-pocket
expenses (see Note 5). Income, common expenses and realized and unrealized gains
and losses are calculated at the Trust level and allocated daily to each class
of shares based on the respective percentage of adjusted net assets at the
beginning of the day.

The Trust declares as daily dividends substantially all of its net investment
income. All dividends are paid on a monthly basis. Short-term capital gain
distributions, if any, may be declared with the daily dividends. Distributions
to shareowners are recorded as of the ex-dividend date. Distributions paid by
the Trust with respect to each class of shares are calculated in the same
manner, at the same time, and in the same amount, except that Class A, Class B,
Class C, Class R, and Investor Class shares can bear different transfer agent
and distribution fees.


                                      -11-


      E.    Repurchase Agreements

With respect to repurchase agreements entered into by the Trust, the value of
the underlying securities (collateral), including accrued interest received from
counter parties, is required to be at least equal to or in excess of the value
of the repurchase agreement at the time of purchase. The collateral for all
repurchase agreements is held in safekeeping in the customer-only account of the
Trust's custodian, or sub custodians. The Trust's investment adviser, Pioneer
Investment Management, Inc. (PIM) is responsible for determining that the value
of the collateral remains at least equal to the repurchase price.

3.    Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Trust that would have been issued at June 30, 2004, in connection with the
proposed acquisition. The number of the shares assumed to be issued is equal to
the net asset value of Safeco Intermediate-Term U.S. Government Fund, as of June
30, 2004, divided by the net asset value per share of the Investor Class shares
of the Trust as of June 30, 2004. The pro forma number of shares outstanding (in
thousands), by class, for the combined fund consist of the following at June 30,
2004:

                         Shares of        Additional Shares    Total Outstanding
                         The Trust         Assumed Issued            Shares
Class of Shares       Pre-Combination     In Reorganization     Post-Combination
- ---------------       ---------------     -----------------     ----------------
Class A                    13,322                                    13,322
Class B                     4,586                                     4,586
Class C                     3,148                                     3,148
Class R                        49                                        49
Investor Class                  -                6,866                6,866

4.    Management Agreement

PIM manages the Trust's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.50% of the Trust's average daily net assets. PIM discontinued the Fund's
expense limitation on May 1, 2003. Prior to May 1, 2003, PIM had agreed not to
impose a portion of its management fee and to assume other operating expenses of
the Trust to the extent necessary to limit Class A expenses to 1.00% of the
average daily net assets attributable to Class A shares; the portion of the
Trust-wide expenses attributable to Class B, Class C and Class R shares were
reduced only to the extent that such expenses were reduced for Class A shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Trust. At June 30, 2004, $128,414 was payable to PIM
related to management fees, administrative fees and certain other services, and
is included in due to affiliates.


                                      -12-


5.    Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Trust at
negotiated rates. Included in due to affiliates is $105,634 in transfer agent
fees payable to PIMSS at June 30, 2004.

6.    Distribution and Service Plans

The Trust adopted Plans of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan,
the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net
assets attributable to Class A shares in reimbursement of such expenditures to
finance activities primarily intended to result in the sale of Class A shares.
Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of
the average daily net assets attributable to each class of shares. The fee
consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class B and Class C shares. Pursuant to the
Class R Plan, the Trust pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $100,070 in distribution fees payable to PFD at June 30, 2004. The
Trust also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Trust to pay securities dealers, plan
administrators or other services organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Trust a
service fee of up to 0.25% of the Trust's daily net assets attributable to Class
R shares held by such plans.

In addition, redemptions of each class of shares (except Investor Class shares)
may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may
be imposed on redemptions of certain net asset value purchases of Class A shares
within one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Redemptions of Class R shares within 18 months of purchase may be subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the 12 months ended
June 30, 2004, CDSCs in the amount of $373,990 were paid to PFD.

Investor Class shares will not be subject to shareholder servicing or
distribution fees. Investor Class shares will convert to Class A shares 24
months after the date on which the acquisition is completed.

7.    Expense Offset Arrangements

The Trust has entered into certain expense offset arrangements with PIMSS,
resulting in a reduction in the Trust's total expenses due to interest earned on
cash held by PIMSS. For the 12 months ended June 30, 2004, the Trust's expenses
were reduced by $6,000 under such arrangements.

(a)   No adjustments are shown to the unaudited pro forma combined schedule of
      investments due to the fact that upon consummation of the merger, no
      securities would need to be sold in order for Pioneer America Income Trust
      to comply with its prospectus restrictions. The foregoing sentence shall
      not restrict in any way the ability of the investment adviser of either of
      the funds from buying or selling securities in the normal course of such
      fund's business and operations.

TBA   (To Be Assigned) securities are purchased on a forward commitment basis
      with an approximate (generally plus/minus 2.5%) principal and no definite
      maturity date period. The actual principal amount and maturity date will
      be determined upon settlement when the specific mortgage pools are
      assigned.

   The accompanying notes are an integral part of these financial statements.

Pioneer America Income Trust

NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
12/31/03
(Unaudited)

1.    General

The accompanying pro forma combined financial statements are presented to show
the effect of the proposed acquisition (the "acquisition") of Safeco
Intermediate-Term U.S. Government Fund by Pioneer America Income Trust.

Under the terms of an Agreement and Plan of Reorganization between the Funds,
the combination of Pioneer America Income Trust and Safeco Intermediate-Term
U.S. Government 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 Safeco Intermediate-Term U.S. Government Fund in exchange
for a new "Investor Class" of shares of Pioneer America Income Trust at net
asset value, which will be established upon consummation of the merger. The
accompanying schedules of investments, statements of assets and liabilities and
the related statements of operations of Pioneer America Income Trust and Safeco
Intermediate-Term U.S. Government Fund have been combined as of and for their
most recent fiscal year ended December 31, 2003. Adjustments have been made to
expenses for duplicate services that would not have been incurred if the merger
took place on January 1, 2003. Following the acquisition, the Pioneer America
Income 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 Pioneer America Income Trust and
Safeco Intermediate-Term U.S. Government Fund included in their respective
annual reports to shareowners dated December 31, 2003.

2.    Organization and Significant Accounting Policies

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.

After the merger, the Trust will consist of five classes of shares - Class A,
Class B, Class C, Class R and Investor Class shares. Class R shares were first
publicly offered on April 1, 2003. Investor Class shares are being offered as
part of the acquisition. Shares of Class A, Class B, Class C, Class R and
Investor Class each represent an interest in the same portfolio of investments
of the Trust and have equal rights to voting, redemptions, dividends and
liquidation, 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 Investor Class
shares.

Each Fund's management has prepared their respective financial information using
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the pro forma financial statements, and the reported amounts of income, expenses
and gains and losses on investments during the reporting periods. Actual results
could differ from those estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust, which are in conformity with those generally accepted in
the investment company industry:


                                      -20-


      A.    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 there are no
other readily available valuation method are valued at their fair values as
determined by, or under the direction of the Trust's Board of Trustees. At
December 31, 2003, there were no securities fair valued. 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 pay downs. 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.

Gains and losses on sales of investments are calculated on the identified cost
method for both financial reporting and federal income tax purposes.

      B.    Federal Income Taxes

Each fund has previously elected to be taxed as a "regulated investment company"
under the Internal Revenue Code. After the acquisition, it will 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 combined capital loss carryforward of $8,538,000 includes a net capital loss
carryforward of $1,398,000 from the merger with Safeco Intermediate-term U.S.
Government Fund, the full use of which may be limited.

      C.    Fund Shares

The Trust records sales and repurchases of its shares as of trade date. Pioneer
Funds Distributor, Inc. (PFD), the principal underwriter for the Trust and a
wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito
Italiano), earned $65,614 in underwriting commissions on the sale of Trust
shares for the year ended December 31, 2003.

      D.    Class Allocations

Distribution fees are calculated based on the average daily net asset value
attributable to Class A, Class B, Class C, Class R, and Investor Class shares of
the Trust, respectively. Shareowners of each class share all expenses and fees
paid to the transfer agent, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), for its services, which are allocated based on the number of
accounts in each class and the ratable allocation of related out-of-pocket
expenses (see Note 5). Income, common expenses and realized and unrealized gains
and losses are calculated at the Trust level and allocated daily to each class
of shares based on the respective percentage of adjusted net assets at the
beginning of the day.

The Trust declares as daily dividends substantially all of its net investment
income. All dividends are paid on a monthly basis. Short-term capital gain
distributions, if any, may be declared with the daily dividends. Distributions
to shareowners are recorded as of the ex-dividend date. Distributions paid by
the Trust with respect to each class of shares are calculated in the same
manner, at the same time, and in the same amount, except that Class A, Class B,
Class C, Class R, and Investor Class shares can bear different transfer agent
and distribution fees.

      E.    Repurchase Agreements

With respect to repurchase agreements entered into by the Trust, the value of
the underlying securities (collateral), including accrued interest received from
counter parties, is required to be at least equal to or in excess of the value
of the repurchase agreement at the time of purchase. The collateral for all
repurchase agreements is held in safekeeping in the customer-only account of the
Trust's custodian, or sub custodians. The Trust's investment adviser, Pioneer
Investment Management, Inc. (PIM) is responsible for determining that the value
of the collateral remains at least equal to the repurchase price.


                                      -21-


3.    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, 2003, in connection with the
proposed acquisition. The number of the shares assumed to be issued is equal to
the net asset value of Safeco Intermediate-Term U.S. Government Fund, as of
December 31, 2003, divided by the net asset value per share of the Investor
Class shares of the Trust as of December 31, 2003. The pro forma number of
shares outstanding (in thousands), by class, for the combined fund consist of
the following at December 31, 2003:

                        Shares of        Additional Shares     Total Outstanding
                        the Trust         Assumed Issued             Shares
Class of Shares      Pre-Combination     In Reorganization      Post-Combination
- ---------------      ---------------     -----------------      ----------------
Class A                   15,468                                     15,468
Class B                    5,591                                      5,591
Class C                    3,775                                      3,775
Class R                       33                                         33
Investor Class                 -                7,492                 7,492


                                      -22-


4.    Management Agreement

PIM manages the Trust's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.50% of the Trust's average daily net assets. PIM discontinued the Fund's
expense limitation on May 1, 2003. Prior to May 1, 2003, PIM had agreed not to
impose a portion of its management fee and to assume other operating expenses of
the Trust to the extent necessary to limit Class A expenses to 1.00% of the
average daily net assets attributable to Class A shares; the portion of the
Trust-wide expenses attributable to Class B, Class C and Class R shares were
reduced only to the extent that such expenses were reduced for Class A shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Trust. At December 31, 2003, $158,222 was payable to
PIM related to management fees, administrative fees and certain other services,
and is included in due to affiliates.

5.    Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Trust at
negotiated rates. Included in due to affiliates is $77,973 in transfer agent
fees payable to PIMSS at December 31, 2003.

6.    Distribution and Service Plans

The Trust adopted Plans of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan,
the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net
assets attributable to Class A shares in reimbursement of such expenditures to
finance activities primarily intended to result in the sale of Class A shares.
Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of
the average daily net assets attributable to each class of shares. The fee
consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class B and Class C shares. Pursuant to the
Class R Plan, the Trust pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $127,966 in distribution fees payable to PFD at December 31, 2003.
The Trust also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Trust to pay securities dealers, plan
administrators or other services organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Trust a
service fee of up to 0.25% of the Trust's daily net assets attributable to Class
R shares held by such plans.

In addition, redemptions of each class of shares (except Investor Class shares)
may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may
be imposed on redemptions of certain net asset value purchases of Class A shares
within one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Redemptions of Class R shares within 18 months of purchase may be subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended
December 31, 2003, CDSCs in the amount of $383,960 were paid to PFD.

Investor Class shares will not be subject to shareholder servicing or
distribution fees. Investor Class shares will be converted to Class A shares 24
months after the date on which the acquisition is completed.

7.    Expense Offset Arrangements

The Trust has entered into certain expense offset arrangements with PIMSS,
resulting in a reduction in the Trust's total expenses due to interest earned on
cash held by PIMSS. For the year ended December 31, 2003, the Trust's expenses
were reduced by $8,000 under such arrangements.
