                    NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                           SCHEDULED FOR [   ], 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 [address] on [ ], 2004 at [ : ] [a/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

                                        1


          "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 substantially similar investment objective and policies as your
          Safeco Fund. In the case of certain Safeco Funds, the Pioneer Fund is
          a newly organized mutual fund with investment objective and policies
          substantially the same 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 [   ], 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]

AN INVESTMENT IN ANY PIONEER FUND IS NOT A BANK DEPOSIT AND IS NOT INSURED OR
GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT
AGENCY.

SHARES OF THE PIONEER FUNDS HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
SECURITIES AND EXCHANGE COMMISSION (THE `SEC"). THE SEC HAS NOT PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

BACKGROUND TO THE REORGANIZATIONS

Safeco Asset Management Company ("SAM"), the Safeco Funds' investment adviser
until August 1, 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 Funds'
shareholders, and the quality of the services offered by Pioneer. At these
meetings, 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.

Pioneer believes that it offers 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
substantially similar investment objective and 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 Funds until August 1, 2004, was
     acquired by Symetra. Symetra informed the Board that it was not interested
     in continuing to provide investment advisor services to the Safeco Funds.
     Therefore, a change in your Safeco Fund's investment advisor 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 the second anniversary of the closing date of
     the Reorganizations 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) 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    Each Safeco Fund will transfer all of its assets to the 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. Holders of all share classes 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, you 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. For a two-year
     period following the Closing Date, Pioneer has agreed to limit each Pioneer
     Fund's total operating expenses (other than extraordinary expenses) for
     Investor Class shares. The expense limitation, if any, applicable to the
     class of shares of the Pioneer Fund into which your Safeco Fund is being
     reorganized is set forth under the discussion of the proposal relating to
     such Reorganization. Pioneer is not required to limit any expenses after
     the second anniversary of the Reorganization.

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.

WHO IS PIONEER

Pioneer is registered as an investment adviser under the Investment Advisers Act
of 1940 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.

                                        6


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 fees and out of pocket expenses incurred as
a result of the Reorganizations.

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 of the acquisition of these assets
and certain covenants from Symetra and SAM, including their assistance in
facilitating the Reorganization and 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 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 0.5% 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 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 ARE INTERIM 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 Reorganization 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 of 1940, as amended (the "Investment Company
Act"), shareholders must approve any new investment adviser to a Safeco Fund.
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 approval of the new adviser is submitted to shareholders within 150
days. Because Pioneer will be making the payment to Symetra discussed above, any
fees that Pioneer would be entitled to under the interim advisory agreement will
be held in escrow until shareholders approval is obtained. If Pioneer is not
approved as investment adviser to a Fund, 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 Fund. If the Reorganizations and
the appointment of Pioneer as interim investment adviser is not approved by
December [ ], 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.

WHAT HAPPENS IF A REORGANIZATION IS NOT APPROVED

If a Reorganization is not approved, the Board for that Safeco Fund will
consider what alternative action to take. Such action could include the
liquidation of the Fund.

WHO IS ELIGIBLE TO VOTE

Shareholders of record on [   ], 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.

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

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

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

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

Each Fund also has risks associated with investing in debt securities. Each Fund
could underperform other investments if:

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

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

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

                                        5


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

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.

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 sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. Past performance before and after taxes
does not indicate future results.

Pioneer Balanced 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.

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

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Balanced
Fund through the Reorganization. In addition, shareholders of your 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

                                        8


Reorganization may purchase Class A Shares of Pioneer Balanced 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
Balanced Fund to the extent the Fund's total ordinary operating expenses
exceeded 0.40% of the Fund's average daily net asset value in a fiscal year.
This arrangement included all fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Balanced Fund to 1.10% 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 Balanced
Fund and two years for Pioneer Balanced Fund and (e) and the Investor Class
shares of Pioneer Balanced 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 Balanced 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 Fund's investment management was necessary.

SECOND, the investment performance of Pioneer Balanced Fund is comparable to the
investment performance of your Fund. For the five year period ended June 30,
2004, Class A shares of Pioneer Balanced Fund had an average annual return of
[xx]% compared to an average annual of the Class A shares and Investor shares of
your Fund of [xx]% and [xx]%, 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 Balanced Fund's lower gross operating expenses and Pioneer's
commitment until the second anniversary of the Reorganization to limit the
ordinary operating expenses (excluding taxes, commissions, interest and
extraordinary expenses) of the Investor Class of Pioneer Balanced Fund to 1.10%
of average daily net assets. This expense ratio is below the gross expenses of
each class of shares of your Fund and is the same or lower than expenses net of
expense reimbursement of each class of shares of your Fund.

FIFTH, the substantially larger size of Pioneer Balanced 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) 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 Balanced Fund received in the
Reorganization will provide Safeco Balanced 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 Balanced Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Balanced 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 Balanced Fund and its
shareholders.

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

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

- -----------------------------------------------------------------------------------------------------------------------------------
Investment objective      Each Fund seeks to provide as high a level of current interest income exempt from federal income tax
                          and California state personal income tax as is consistent with the relative stability of capital.
                          During normal market conditions, each Fund will not invest less than 80% of its net assets in
                          obligations the interest on which is exempt from federal income tax and from California state personal
                          income tax.

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

- -----------------------------------------------------------------------------------------------------------------------------------
Primary investments       To achieve its investment objective, each Fund invests primarily in investment-grade municipal bonds
                          issued by the state of California or its political subdivisions and having average maturities of 15
                          years or longer.  Under normal circumstances, each Fund invests:
                          o    At least 80% of its assets in securities the interest on which is exempt from federal income tax and
                               California personal income tax
                          o    At least 65% of its assets in investment-grade municipal bonds with a maturity of more than one year
                          o    Up to 20% of its assets in unrated municipal bonds, as long as Pioneer determines they are of
                               comparable quality to investment-grade securities

Investment strategies     When evaluating a bond to buy, each Fund's advisor considers among other things:
                          o    Yield
                          o    Maturity
                          o    Structural features such as an issuer's right to buy the bond back at a stated price (a "call") or
                               the Fund's right to require the issuer to buy the bond back at a stated price (a "put")
                          o    Credit quality (including the underlying rating of insured bonds)
                          o    The project the issuer is financing
                          o    The original offering price
                          o    Any state or local tax exemption
                          o    The amount of discount off or premium on the stated principal amount of the bond represented by the
                               price offered
                          o    Whether the bond appears to offer the best overall value when compared to other available bonds

                          Each Fund's advisor favors long-term maturity bonds in essential services that offer a significant
                          degree of protection against issuer repurchase rights prior to maturity and good value relative to
                          their peers.  Each Fund's advisor may use the rating services provided by Moody's, S&P, or Fitch.  Bond
                          ratings indicate an issuer's financial strength and ability to meet its debt obligations.

                          Each Fund may sell bonds when:
                          o    They become fully valued
                          o    More attractively valued bonds become available; or

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

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.

PAST PERFORMANCE

Set forth below is performance information for Safeco California TF Income Fund.
The bar charts show how Safeco California TF 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 sales taxes) for Safeco California TF Income Fund over time for each class
of shares (including deductions for sales charges) compared with a broad-based
securities market index. Past performance before and after taxes does not
indicate future results. Because Pioneer California TF 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 Fund who become shareholders of record of Pioneer
California TF Income Fund through the Reorganization. In addition, shareholders
of your 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 TF 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 TF Income Fund to the extent the Fund's total ordinary operating
expenses exceeded 0.40% of the Fund's average daily net asset value in a fiscal
year. This arrangement included all fund operating expenses except management
fees, Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary operating expenses) of the
Investor Class shares of Pioneer California TF 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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
TF Income Fund and two years for Pioneer California TF Income Fund and (e) and
the Investor Class shares of Pioneer

                                        7


California TF 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 TF 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 Fund's investment management 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer California TF
Income Fund to 0.63% of average daily net assets. This expense ratio is no
higher than both the gross expenses and expenses net of expense reimbursement of
the Class A shares and Investor Class shares of your Fund. Although you will
experience higher expenses once

                                        8


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

The board of trustees of Pioneer California TF Income Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer California
TF 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 TF Income Fund.

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

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

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

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

o    Value stocks fall out of favor with investors

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

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

PAST PERFORMANCE

Set forth below is performance information for each Fund. The bar charts show
how each Fund's total return (not including any deduction for sales charges) has
varied from year to year for each full calendar year. The tables show average
annual total return (before and after sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. Past performance before and after taxes
does not indicate future results.

(1)  The Fund commenced operations on February 13, 1928.
(2)  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.
(3)  The S&P 500 Index, an unmanaged index of 500 stocks, is for reference only,
     does not mirror the Fund's investments, and reflects no deduction for fees,
     expenses or taxes.

Pioneer 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.

THE FUNDS' FEES AND EXPENSES

Shareholders of both Funds pay various fees and expenses, either directly or
indirectly. The tables below show the fees and expenses that you would pay if
you were to buy and hold shares of each Fund. The expenses in the tables
appearing below are based on (i) for the Safeco Core Equity Fund, the expenses
of Safeco Core Equity Fund for the period ended December 31, 2003 and (ii) for
Pioneer Fund, the expenses of Pioneer 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 Fund who become shareholders of record of Pioneer Fund
through the Reorganization. In addition, shareholders of your 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 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 Core
Equity Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Fund to 1.02% 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 Fund.

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 Core Equity
Fund and two years for Pioneer Fund and (e) and the Investor Class shares of
Pioneer 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 Core Equity 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 Fund's investment management was necessary.

SECOND, the historical strong investment performance of Pioneer Fund is superior
to your Fund's investment performance. For the one, five and 10 year periods
ended June 30, 2004, Class A shares of Pioneer Fund had an average annual return
of ___%; ___%; and __% compared to an average annual return of the Class A
shares and Investor share of ___% and __% (one year), __% and __% (five years)
and __% and __% (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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 Fund's lower operating expenses and Pioneer's commitment until
the second anniversary of the Reorganization to limit the ordinary operating
expenses (excluding taxes, commissions, interest and extraordinary expenses) of
the Investor Class of Pioneer Fund to 1.02% of average daily net assets. This
expense ratio is below both the gross expenses and expenses net of expense
reimbursement of the class shares of your Fund. While you will experience higher
expenses once the Investor Class shares convert to Class A shares after two
years, the Class A expense ratio for the most recent fiscal year, was 1.09% of
average daily net assets, which was below the net expenses of the Class A shares
of your Fund and only four basis point above the net expenses of the Investor
Class of your Fund.

FIFTH, the substantially larger size of Pioneer 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) 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 Fund received in the
Reorganization will provide Safeco Core Equity 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

                                        9


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

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

BOARD'S EVALUATION AND RECOMMENDATION

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

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

                         growth potential.

Investment strategies    When evaluating a stock to buy for each Fund, Pioneer considers factors such as:

                         o    The strength of the company's balance sheet
                         o    The quality of the management team
                         o    The rate at which the company's earnings are projected to grow
                         o    Whether the company's stock may be trading at a discount relative to its industry peers or the
                              overall markets

                              hold a larger position in the stock than
                              Pioneer wants;

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 capital growth, you could lose money on your investment
or not make as much as if you invested elsewhere if:

o    The stock market goes down (this risk factor may be greater in the short
     term)
o    Growth stocks fall out of favor with investors
o    The Fund's investments do not have the growth potential originally expected
o    The Fund's shares may be subject to frequent and more significant changes
     in value than the stock market in general due to the volatility of some of
     the smaller companies in which it invests
o    During periods of market concern about inflation or deflation, some
     securities in which the Fund invests may become more volatile or decline in
     value

                                        4


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

PAST PERFORMANCE

Set forth below is performance information for Safeco Opportunities Fund. The
bar chart shows how Safeco Opportunities 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 sales taxes)
for Safeco Opportunities Fund over time for each class of shares (including
deductions for sales charges) compared with a broad-based securities market
index. Past performance before and after taxes does not indicate future results.
Since Pioneer Opportunities Fund has not yet commenced investment operations, it
has no prior performance.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer
Opportunities Fund through the Reorganization. In addition, shareholders of your
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 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
Opportunities Fund to the extent the Fund's total ordinary operating expenses
exceeded 0.40% of the Fund's average daily net asset value in a fiscal year.
This arrangement

                                        6


included all fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Opportunities Fund to 1.05% 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 and Pioneer Opportunities Fund's gross
operating expenses remain the same, (e) the expense limitations are in effect
for five years for Safeco Opportunities Fund and two years for Pioneer
Opportunities Fund and (f) and the Investor Class shares of Pioneer
Opportunities 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 Opportunities 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 Fund's investment management 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer Opportunities Fund
to 1.05% 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 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) 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 Opportunities Fund received in the
Reorganization will provide Safeco Opportunities 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 Trustees of Pioneer Opportunities Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Opportunities
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 Opportunities Fund and
its shareholders.

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. 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:

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

                                        5


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.

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 sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. 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.

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

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer High
Yield Fund through the Reorganization. In addition, shareholders of your 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 Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and 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 Fund.

                                        8


(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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
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 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 Fund's investment management was necessary.

SECOND, the investment performance of Pioneer High Yield Fund, which has one of
the best performance records of any mutual fund specializing 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 ___% and ___%
compared to an average annual of the Class A shares and Investor

                                        9


Class shares of ___% and ___% (one year) and ___% and ___% (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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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
ordinary operating expenses (excluding taxes, commissions, interest and
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 expense reimbursement of each class of shares of your 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 for the most
recent fiscal year, were 1.06% of average daily net assets, which was below the
net expenses of the Class A shares of your Fund and only one basis point above
the net expenses of the Investor Class of your 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) 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 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.

Yield Fund's shares that will actually be received and distributed.

Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Fund. Similarly, the

Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer High Yield 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 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 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

                                        5


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

Government sponsored entities such as the Federal Home Loan Mortgage Corporation
(Freddie Mac), the Federal National Mortgage Association (FNMA) and the Federal
Home Loan Banks (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 mortgaged-backed
securities, its exposure to prepayment and extension risks may be greater than
if it invested in other fixed income securities.

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 sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. 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 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

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Bond Fund
through the Reorganization. In addition, shareholders of your 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 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 IT Bond
Fund to the extent the Fund's total ordinary operating expenses exceeded 0.40%
of the Fund's average daily net asset value in a fiscal year. This arrangement
included all fund operating expenses except management fees, Rule 12b-1 fees,
brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and 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.

                                        8


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

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 one year for Safeco IT 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 IT 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 Fund's investment management was necessary.

                                        9


SECOND, the investment performance of Pioneer Bond Fund, which has outperformed
your Fund over the most recent one, five and ten year periods (one year), ___%
and ___% (five years) and ___%, and ___% (ten years). 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 ___%, ___% and ___% compared to an average annual of
the Class A shares and Investor Class shares of [xx]% and [xx]%, 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 operating expenses
(excluding taxes, commissions, interest and 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 Fund. In addition, the next
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 Fund and the same as
the net expense of the Investor class. The trustees also considered the
difference in the investment policies of the two Funds, particularly by Pioneer
Bond Fund's ability to invest in securities with longer maturity than your Fund.
While this may result in the Prime Bond Fund having greater risk of volatility
of net asset value than your Fund, the trustees believe this then functions in
favor of the Reorganization mitigated this risk. This expense ratio is no higher
than both the gross expenses and expenses net of expense reimbursement of the
Class A and Investor Class shares of your 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 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) 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 Fund. While this may result in
Pioneer Bond Fund having greater volatility of net asset value than your 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.

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 Fund can invest in securities
of longer maturity than your Fund, an investment in Pioneer Tax Free 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

                                        5


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.

Pioneer Tax Free 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 Shares class.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Tax Free
Fund through the Reorganization. In addition, shareholders of your 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 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 IT Muni
Bond Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all Fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Tax Free 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 Fund.

                                        8


(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 IT Muni Bond
Fund and two years for Pioneer Tax Free Fund and (f) and the Investor Class
shares of Pioneer Tax Free 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 IT Muni 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 Fund's investment management was necessary.

SECOND, the historical investment performance of Pioneer Tax Free Fund and your
Fund are comparable. For the one, five and ten year periods ended June 30, 2004,
Class A shares of Pioneer Tax Free Fund had an average annual return of ___%,
____% and ____% compared to an average annual of the Class A shares and Investor
Class shares of ___% and ___% (one year), and __%

                                        9


(five years) and ____% and ____% (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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 Fund's lower operating expenses and Pioneer's
commitment until the second anniversary of the Reorganization to limit the
ordinary operating expenses (excluding taxes, commissions, interest and
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 Fund are below both the gross expenses and expenses
net of expense reimbursement of each class of shares of your 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 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) 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.

The trustees also considered the difference in the investment policies of the
two Funds, particularly Pioneer Tax Free Fund's ability to invest in securities
with long maturities than your Fund. While the difference in policy may result
in Pioneer Tax Free Fund having greater risks of volatility of net assets value
than your Fund, the trustees believe that the factors in favor of the
reorganizing mitigated the risk.

SEVENTH, the trustees also considered the differences in the investment policies
of the two Funds, particularly Pioneer Tax Free Fund's ability to invest in
securities with longer maturities than your Fund. While this may result in
Pioneer Tax Free Fund having greater volatility of net asset value than your
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 Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Tax Free 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 Fund and its
shareholders.

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

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

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 effect 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 Fund and consequently may have
greater risk. However, your 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.

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 sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. 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.

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

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer America
Income Trust through the Reorganization. In addition, shareholders of your 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 U.S.
Government Fund to the extent the Fund's total ordinary operating expenses
exceeded 0.40% of the Fund's average daily net asset value in a fiscal year.
This arrangement included all Fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 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 U.S. GOVERNMENT TRUST (A SERIES OF A DELAWARE
STATUTORY TRUST)

o    GOVERNANCE AND MANAGEMENT. Safeco 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 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 U.S. Government Fund
     without par value. As of the date of this prospectus and proxy statement,
     the Trustees have authorized shares of Safeco U.S. Government Fund and have
     authorized the issuance of four classes of shares of Safeco U.S. Government
     Fund, designated as Class A, Class B, Class C and Investor Class Shares.
     The shares of each class of Safeco 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 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 the Fund. Unless otherwise
     required by the 1940 Act, the Fund has have 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 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 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    SHARE CAPITAL AND CLASSES. Pioneer America Income Trust is authorized to
     issue shares of capital stock and to increase or decrease the aggregate
     number of shares of capital stock or the number of shares of stock 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
     registered open-end investment companies, are not required to hold annual
     shareholder meetings. Unless otherwise required by the 1940 Act, the Papp
     Funds have no intention of holding annual meetings of stockholders.
     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 STOCKHOLDERS. Shareholders of a Massachusetts business trust
     may, under certain circumstances, be held personally liable for the
     obligations of the trust. However, the Declaration contains an express
     disclaimer of shareholder liability for acts or obligations of the Fund or
     any series of the Fund and provides that notice of such disclaimer may be
     given in each agreement, obligation or instrument entered into or executed
     by the Fund or its Trustees. Moreover, the Declaration provides for the
     indemnification out of Fund property of any shareholders held personally
     liable for any obligations of the Fund or any series of the Fund. The
     Declaration also provides that the Fund shall, upon request, assume the
     defense of any claim made against any shareholder for any act or obligation
     of the Fund 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

                                       10


     which the fund itself will be unable to meet its obligations. In light of
     the nature of the Fund's business and the nature and amount of its assets,
     the possibility of the Fund'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 U.S. Government 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 Fund's investment management was necessary.

SECOND, the performance of Pioneer America Income Trust is generally consistent
with the historical investment performance of your 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 [xx]% compared to an average annual of the
Class A shares and Investor Class shares of [xx]% and [xx]% (one year), ____%
and ____% (five years) and ___% and ___% (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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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
ordinary operating expenses (excluding taxes, commissions, interest and
extraordinary operating expenses) of the Investor Class of Pioneer America
Income Trust to 0.74% of average daily net assets. The estimated experience of
the Investor class of Pioneer America Income Trust are below both the gross
expenses and expenses net of expense reimbursement of the end class of shares of
your 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 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) 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 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 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."

                                       11


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.

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

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

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

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

Investing in non-U.S. issuers may involve unique risks compared to investing in
securities of U.S. issuers. Some of these risks do not apply to larger, more
developed markets. These risks are more pronounced to the extent the Fund
invests in issuers in countries with emerging markets or if the fund invests
significantly in one country. These risks may include:

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

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

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

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

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

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

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.

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 sales taxes) for each Fund over time for
each class of shares (including deductions for sales charges) compared with a
broad-based securities market index. Past performance before and after taxes
does not indicate future results.

Pioneer International Equity 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.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer
International Equity Fund through the Reorganization. In addition, shareholders
of your 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 International Equity 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
International Stock Fund to the extent the Fund's total ordinary operating
expenses exceeded 0.40% of the Fund's average daily net asset value in a fiscal
year. This arrangement included all fund operating expenses except management
fees, Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer International Equity Fund to 1.40% 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 Fund.

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
International Stock Fund and two years for Pioneer International Equity Fund and
(e) and the Investor Class shares of Pioneer International Equity 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 International Stock 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 Fund's investment management 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer International
Equity Fund to 1.40% of average daily net assets. The estimated expenses of the
Investor Class of Pioneer International Equity Fund are lower than both the
gross and net expenses of the expense limits of each class of shares of your
Fund.

FOURTH, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker) 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 International Equity Fund received
in the Reorganization will provide Safeco International Stock 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 International Equity Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer
International Equity 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
International Equity Fund and its shareholders.

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

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

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

o Growth stocks fall out of favor with investors

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

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

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

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

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

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

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

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

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.

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 sales taxes) for each Fund
over time for each class of shares (including deductions for sales charges)
compared with a broad-based securities market index. Past performance before and
after taxes does not indicate future results.

Pioneer Growth Shares' 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.

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

expenses of Pioneer Growth Shares for the period ended December 31, 2003. Future
expenses for all share classes may be greater or less.

Pioneer family of funds through such account in the future without paying this
sales charge.

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

(9) [SAM voluntarily reimburses the Fund to the extent that its total expenses
exceed the rate of 1.15% per annum of the Fund's average daily net assets. SAM
does not have the right to recapture waived fees or reimbursed expenses under
this arrangement.]

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 one year for Safeco LC Growth Fund
and two years for Pioneer Growth Shares and (e) and the Investor Class shares of
Pioneer Growth Shares 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 LC Growth 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 Fund's investment management was necessary.

SECOND, Pioneer Growth Shares has a strong short term performance record and a
substantially longer performance history. For the one year period ended June 30,
2004, Class A shares of Pioneer Growth Shares had an average annual return of
[xx]% compared to an average annual of the Class A shares and Investor share of
[xx]% and [xx]%, 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 Growth Shares' lower operating expenses and Pioneer's commitment
until the second anniversary of the Reorganization to limit the ordinary
operating expenses (excluding taxes, commissions, interest and extraordinary
expenses) of the Investor Class of Pioneer Growth Shares to 1.15% of average
daily net assets. The estimated expense ratio of the Investor

                                       10


Class of Pioneer Growth Shares is lower than the gross expenses of each class of
shares of your Fund. The expense limitation applicable to Investor Class Shares
of Pioneer Growth Shares is the same as the voluntary expense limit applicable
to your Fund, and Pioneer has contractually agreed to keep that limit in place
for two years while the expense limit applicable to your Fund could be
terminated at any time. While you will experience higher expenses once the
Investor Class shares convert to Class A shares after two years, the Class A
expense ratio for the most recent fiscal year, was 1.45% of average daily net
assets, which was below the expenses of the class of shares of your Fund.

FIFTH, the substantially larger size of Pioneer Growth Shares 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) 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 Growth Shares received in the
Reorganization will provide Safeco LC Growth 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 Growth Shares also considered that the
Reorganization presents an excellent opportunity for the Pioneer Growth Shares
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 Growth Shares and its
shareholders.

It is impossible to predict how many shares of Pioneer Growth Shares will
actually be received and distributed by your Fund on the Reorganization date.
The table should not be relied upon to determine the amount of Pioneer Growth
Shares' 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 Fund. Similarly, the
board of trustees of Pioneer

                                       11


Growth Shares, including its Independent Trustees, approved the Reorganization.
They also determined that the Reorganization is in the best interests of Pioneer
Growth Shares.

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

                          securities, SAM historically analyzed various     investments.  Pioneer evaluates a security's
                          valuation measures such as the ratio of a         potential value, including the attractiveness of its
                          company's price-to-cash flow compared to its      market valuation, based on the company's assets and

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

o    Stock market goes down (this risk may be greater in the short-term)

o    Value stocks fall out of favor with investors

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

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

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.

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 sales taxes) for each Fund
over time for each class of shares (including deductions for sales charges)
compared with a broad-based securities market index. Past performance before and
after taxes does not indicate future results.

Pioneer Value 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.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Value
Fund through the Reorganization. In addition, shareholders of your 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 Value 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 LC
Value Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Value Fund to 1.10% 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 Fund.

                                        8


(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 LC Value
Fund and two years for Pioneer Value Fund and (e) and the Investor Class shares
of Pioneer Value 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 LC Value 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 Fund's investment management was necessary.

SECOND, Pioneer Value Fund's short and long-term performance record is superior
to the performance record of your Fund. For the one, five and ten year periods
ended June 30, 2004, Class A shares of Pioneer Value Fund had an average annual
return of

                                        9


[xx]% ___%, and ___% compared to an average annual of the Class A shares and
Investor Class shares of 16.75% and 24.20% (one year) -3.39% and -2.01% (five
year) and 5.98% and 6.86% (ten year), respectively, during the same period. In
addition, the Trustees considered the track record of Pioneer in managing equity
and fixed income mutual funds.

THIRD, the resources of Pioneer. At 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 Value Fund's lower operating expenses and Pioneer's commitment
until the second anniversary of the Reorganization to limit the ordinary
operating expenses (excluding taxes, commissions, interest and extraordinary
expenses) of the Investor Class of Pioneer Value Fund to 1.10% of average daily
net assets. The estimated expense ratio of the Investor Class shares of Pioneer
Value Fund is no lower than both the gross expenses and expenses net of expense
reimbursement of each class of shares of your Fund. Although you will experience
higher expenses once the Investor Class shares convert to Class A shares after
two years, the Class A expense ratio for the most recent fiscal year was 1.19%
of average daily net assets, which was below the total annual expenses of the
Class A shares of your Fund.

FIFTH, the substantially larger size of Pioneer Value 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) 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 Value Fund received in the
Reorganization will provide Safeco LC Value 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 Value Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Value 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 Value Fund and its
shareholders.

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

board of trustees of Pioneer Value Fund, including its Independent Trustees,
approved the Reorganization. They also determined that the Reorganization is in
the best interests of Pioneer Value Fund.

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL

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

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.

(1) No sales load will apply to shares received in the Reorganization
by shareholders of your Fund who become shareholders of record of
Pioneer Cash Reserves Fund through the Reorganization. In addition,
shareholders of your 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 to the extent the Fund's total ordinary
operating expenses exceeded 0.30% of the Fund's average daily net
asset value in a fiscal year. This arrangement included all Fund
operating expenses except management fees, Rule 12b-1 fees, brokerage
commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the
closing of the Reorganization, Pioneer will limit the ordinary
operating expenses (excluding taxes, commissions, interest and
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 Fund.

(6) A contingent deferred sales charge may apply if you redeem Class B
shares of your 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.

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 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 Fund's investment
management was necessary.

SECOND, the investment performance of Pioneer Cash Reserves Fund is
comparable to the historical investment performance of your 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
___%, ___%, and ___%, compared to an average annual of the Class A
shares and Investor Class shares of ___% and ___%, (one year) ___% and
___% (five years) and ___% and ___% (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 by UniCredito Italiano S.p.A. were
approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the
Investor Class of Pioneer Cash Reserves Fund to 0.71% of average daily
net assets. This expense ratio is no higher than both the gross
expenses and expenses net of expense reimbursement of the Class A and
Investor Class shares of your 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.

                                        9


FIFTH, shareholders who own shares in their name as of the closing of
the Reorganization (i.e., not in the name of a broker) 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.

Independent Trustees, approved the Reorganization. In particular, the
Trustees determined that the Reorganization is in the best interests

Reserves Fund, including its Independent Trustees, approved the

best interests of Pioneer Cash Reserves 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 capital appreciation, you could lose money on your
investment or not make as much as if you invested elsewhere if:

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

o    Mid-size or value stocks fall out of favor with investors

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

                                        5


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

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

o    Have more limited product lines and capital resources

o    Experience sharper swings in market values

o    Be harder to sell at the times and prices Pioneer thinks appropriate

o    Offer greater potential for gain and loss

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

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

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

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

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

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

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

Pioneer Mid Cap 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.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Mid Cap
Fund through the Reorganization. In addition, shareholders of your 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 Mid Cap 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 Multi
Cap Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all Fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer Mid Cap Fund to 1.10% 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 Multi Cap
Fund and two years for Pioneer Mid Cap Fund and (f) and the Investor Class
shares of Pioneer Mid Cap 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 Multi Cap 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 Fund's investment management was necessary.

SECOND, the performance of Pioneer Mid Cap Fund is generally consistent with the
historical investment performance of your Fund. For the one and five year
periods ended June 30, 2004, Class A shares of Pioneer Mid Cap Fund had an
average annual return of ___% and ___% compared to an average annual of the
Class A shares and Investor Class shares of ___% and ___% (one year) and ___%
and ____% (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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer Mid Cap Fund to
1.10% of average daily net assets. The estimated expenses of the Investor Class
shares of Pioneer Mid Cap Fund are below both the gross expenses and expenses
net of expense reimbursement of each class of shares of your Fund. Although you
will experience higher

                                       10


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 Mid Cap 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) 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 Mid Cap Fund received in the
Reorganization will provide your Fund's 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 Mid Cap Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Mid Cap 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 Mid Cap Fund and its
shareholders.

                          Mary Metastasio (since 2003 and until July 31,     Mr. Taubes joined Pioneer as a senior vice president
                          2004)                                              in September 1998 and has been an investment
                                                                             professional since 1982.
                          Currently Pioneer is acting as investment
                          adviser to the Fund.  The Portfolio Manager of
                          the Pioneer Fund, as indicated in the next
                          column, currently manages your Safeco 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.  During normal market conditions, each Fund will
                          not invest less than 80% of its net assets in obligations the interest on which is exempt from federal
                          income tax.

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

- ----------------------------------------------------------------------------------------------------------------------------------
Primary investments       To achieve its investment objective, each Fund invests primarily in municipal bonds rated investment
                          grade or better with average maturities of 15 years or longer.  Under normal circumstances, each Fund
                          invests:
                          o    at least 80% of its assets in investment-grade municipal bonds with a maturity of more than one
                               year and the interest on which is exempt from federal income tax; and
                          o    up to 20% of its assets in unrated municipal bonds, as long as the advisor determines they are of
                               comparable quality to investment-grade securities.

                          Each Fund will not invest in securities the interest on which is a tax preference item for purposes of
                          the federal alternative minimum tax.

Investment strategies     When evaluating a bond to buy, each Fund's advisor considers among other things:

                          o    Yield
                          o    Maturity
                          o    Structural features such as an issuer's right to buy the bond back at a stated price (a "call") or
                               the Fund's right to require the issuer to buy the bond back at a stated price (a "put")
                          o    Credit quality (including the underlying rating of insured bonds)
                          o    The project the issuer is financing
                          o    The original offering price
                          o    Any state or local tax exemption
                          o    The amount of discount off or premium on the stated principal amount of the bond represented by the
                               price offered

                          Each Fund's advisor may use the rating services provided by Moody's, S&P, or Fitch.  Bond ratings
                          indicate an issuer's financial strength and ability to meet its debt obligations.

                          Each Fund may sell bonds when:

                          o    They become fully valued
                          o    More attractively valued bonds become available
                          o    Cash is needed to meet shareholder redemptions

                          Because it often takes years for attractive relative valuations to be recognized by the municipal
                          securities market, turnover of each Fund's portfolio can be low.

- ----------------------------------------------------------------------------------------------------------------------------------
Other investments         Each Fund will limit its investment in municipal obligations the interest on which is payable from the
                          revenues of similar types of projects less than 25% of each Funds' total assets.  As a matter of
                          operating policy, "similar types of projects" may include sports, convention or trade show facilities;
                          airports or mass transportation; sewage or solid waste disposal facilities; or air and water pollution
                          control projects.

                          Each Fund may invest in any of the following short-term, tax-exempt obligations: municipal notes of
                          issuers rated, at the time of the purchase, within one of the three highest grades assigned by a
                          nationally recognized statistical rating organization ("NRSRO"); unrated municipal notes offered by
                          issuers having outstanding municipal bonds rated within one of the three highest grades assigned by an
                          NRSRO; notes issued by or on behalf of municipal issuers that are guaranteed by the U.S. government;
                          tax-exempt commercial paper assigned one of the two highest grades by an NRSRO; certificates of deposit
                          issued by banks with assets of $1,000,000,000 or more; and municipal obligations that have a maturity
                          of one year or less from the date of purchase.

                          Each Fund may invest in obligations of the U.S. government, its agencies or instrumentalities or in
                          qualified repurchase agreements, the net interest on which is taxable for federal income tax purposes.

                          Each Fund will limit its investment in securities whose issuers are located in the same state to less
                          than 25% of each Fund's total assets.

- ----------------------------------------------------------------------------------------------------------------------------------
Temporary defensive       The Fund may hold cash or as a temporary           The Fund may invest all or part of its assets in
strategies                defensive measure when market conditions so        securities with remaining maturities of less than one
                          warrant.                                           year, cash equivalents or may hold cash.

- ----------------------------------------------------------------------------------------------------------------------------------
Diversification           Each Fund is diversified for the purpose of the Investment Company Act, and each Fund is subject to
                          diversification requirements under the Code.

- ----------------------------------------------------------------------------------------------------------------------------------
Industry concentration    Each Fund will not make investments that will result in the concentration (as that term may be defined
                          in the 1940 Act, any rule or order thereunder, or SEC staff interpretation thereof) of its investments
                          in the securities of issuers primarily engaged in the same industry, provided that this restriction
                          does not limit each Fund from investing in obligations issued or guaranteed by the U.S. government, its
                          agencies or instrumentalities.

- ----------------------------------------------------------------------------------------------------------------------------------
Restricted and illiquid   If immediately after and as a result of such action the value of the following securities, in the
securities                aggregate, would exceed 10% of the Fund's net assets, the Fund will not (i) purchase securities for
                          which there is no readily available market, (ii) purchase time deposits maturing in more than seven
                          days, (iii) purchase over-the-counter (OTC) options or hold assets set aside to cover OTC options
                          written by the Fund, (iv) enter into repurchase agreements maturing in more than seven days, or (v)
                          invest in interests in real estate investment trusts which are not readily marketable or interests in

                          NASDAQ Stock Market.

Borrowing                 Each Fund may borrow money (i) from banks  or (ii) by engaging in reverse repurchase agreements. Each
                          Fund will not commit to additional securities purchases if total outstanding borrowings are equal to 5%

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

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.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer Bond Fund
through the Reorganization. In addition, shareholders of your 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 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 to the extent the Fund's total ordinary operating expenses
exceeded 0.40% of the Fund's average daily net asset value in a fiscal year.
This arrangement included all fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary operating expenses) of the
Investor Class shares of Pioneer 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 Fund.

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

                                        7


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 (e) 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 Fund's investment management was necessary.

SECOND, the significant experience and resources of Pioneer in managing
portfolios of tax exempt securities. At June 30, 2004, Pioneer Managed Portfolio
of tax exempt securities with total assets of approximately $_____ 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 in Italy, providing investment
management and financial services to mutual funds, institutional and other
clients. As of June 30, 2004, assets under management by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 Fund's shareholders through exchanges. In addition, Pioneer
offers shareholders additional options for their accounts, including

                                        8


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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer Municipal Bond Fund
to 0.62% of average daily net assets. This expense ratio is no higher than both
the gross expenses and expenses net of expense reimbursement of the Class A
shares and Investor Class shares of your 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, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker) 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.

CAPITALIZATION

The following table sets forth the capitalization of each fund, as of December
31, 2003, and the PRO FORMA combined capitalization of both funds as if the
Reorganization had occurred on that date.

It is impossible to predict how many shares of Pioneer Municipal Bond Fund will
actually be received and distributed by your 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 Fund. Similarly, the
board of trustees of Pioneer

                                        9


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.

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

Investment Strategies     When evaluating a stock to buy for the Fund,       Pioneer uses a "value" approach to select the Fund's
                          SAM historically looked for companies having       investments.  Pioneer seeks securities selling at
                          one or more of the following characteristics:      substantial discounts to their underlying values and
                          o    Long-term potential for above-average or      then holds these securities until the market values

COMPARISON OF PRINCIPAL RISKS OF INVESTING IN THE FUNDS

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

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

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

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

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

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

o    Have more limited product lines and capital resources

o    Experience sharper swings in market values

o    Be harder to sell at the times and prices Pioneer thins appropriate

o    Offer greater potential for gain and loss

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.

(1)  The Fund commenced operations on February 28, 1997.
(2)  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.
(3)  The Russell 2000 Value Index, an unmanaged index of value stocks in the
     Russell 2000 Index of small-capitalization U.S. stocks, is for reference
     only, does not mirror the Fund's investments, and reflects no deduction for
     fees, expenses or taxes.

Pioneer SC Value 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.

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer SC Value
Fund through the Reorganization. In addition, shareholders of your 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 SC Value 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 SC
Value Fund to the extent the Fund's total ordinary operating expenses exceeded
0.40% of the Fund's average daily net asset value in a fiscal year. This
arrangement included all fund operating expenses except management fees, Rule
12b-1 fees, brokerage commissions, taxes, interest, and extraordinary expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer SC Value Fund to 1.15% of average daily net assets.

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

                                        8


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

(6) Purchases of $1,000,000 or more of Class A shares of your 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 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.

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 SC Value
Fund and two years for Pioneer SC Value Fund and (e) and the Investor Class
shares of Pioneer SC Value 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 SC Value 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 Fund's investment management was necessary.

SECOND, the long-term investment performance of Pioneer SC Value Fund is
superior to your Fund's performance, although your Fund had better performance
during the most recent 12 month period. For the five year period ended June 30,
2004, Class A

                                        9


shares of Pioneer SC Value Fund had an average annual return of [xx]% compared
to an average annual of the Class A shares and Investor Class shares of [xx]%
and [xx]%, 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer SC Value Fund to
1.15% of average daily net assets. This expense ratio is no lower than both the
gross expenses and expenses net of expense reimbursement of the Class A, Class B
and Class C shares of your Fund and lower than the gross and the same as the net
expense of your Fund's Investor Class shares. Although without the expense
limitation Pioneer SC Value Fund's expenses are significantly higher than your
Fund's net expenses, the trustees believe that Pioneer SC Value Fund offers the
potential for lower expenses through economies of scale.

FIFTH, the substantially larger size of Pioneer SC Value 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) 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 SC Value Fund received in the
Reorganization will provide Safeco SC Value 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 SC Value Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer SC Value 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 SC Value Fund and its
shareholders.

CERTAIN AGREEMENTS BETWEEN PIONEER AND SYMETRA

Pioneer is supporting the Reorganizations because it believes that it offers
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. 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 of that 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 liabilities with respect to
the management of the Safeco Funds prior to the closing of the Reorganizations,
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

                                       10


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, PFD, the principal underwriter of the Pioneer Funds, shall
make payments to Safeco Securities 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 Funds, (ii) PFD will also make additional payments out of
its own resources to Safeco Securities in connection with purchases of Class A
shares of the Pioneer Funds by former shareholders of the Funds; and (iii)
Symetra and SAM will be subject to certain non-competition provisions.

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

THE TRUSTEES RECOMMEND THAT THE SHAREHOLDERS OF YOUR FUND VOTE FOR THE PROPOSAL
TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

- ------------------------------------------------------------------------------------------------------------------------------------
                       
Investment objective      Each Fund seeks to provide as high a level of current income exempt from federal income tax as is
                          consistent with a portfolio of high-quality, short-term municipal obligations selected on the basis of
                          liquidity and preservation of capital.

                          Each Fund provides written notice to shareholders at least 60 days prior to any change to its investment
                          objective as described above.

- ------------------------------------------------------------------------------------------------------------------------------------
Primary investments       To achieve its investment objective, each Fund will purchase only high-quality securities having minimal
                          credit risk with remaining maturities of 397 days or less.

- ------------------------------------------------------------------------------------------------------------------------------------
Investment strategies     Each Fund may purchase only high-quality securities that the investment adviser believes present minimal
                          credit risks. To be considered high quality, a security must be rated, or the issuer must have received a
                          rating for a comparable short-term security, in accordance with applicable rules in one of the two highest
                          categories for short-term securities by at least two nationally recognized rating services (or by one, if
                          one rating service has rated the security); or, if unrated, the security must be judged by the investment
                          adviser to be of equivalent quality.

                          Each Fund may not invest more than 5% of its total assets in second tier securities. In addition, the each
                          Fund may not invest more than 1% of its total assets or $1 million (whichever is greater) in the second
                          tier securities of a single issuer.

                          Each Fund may invest in:
                          o  Variable and floating rate instruments that change interest rates periodically to keep their market
                             value near par

                          o Put bonds, which allow the holder to redeem the issue on specified dates before maturity and receive
                            full face value
                          o Tax-exempt commercial paper
                          o Restricted securities that are exempt from registration requirements and eligible for resale to
                            qualified institutional investors, such as mutual funds under Rule 144A of Section 4(2)

- ------------------------------------------------------------------------------------------------------------------------------------
Other investments         Each Fund will limit its investment in municipal obligations the interest on which is payable from the
                          revenues of similar types of projects to less than 25% of the Fund's total assets. As a matter of
                          operating policy, "similar types of projects" may include sports, convention or trade show facilities;
                          airports or mass transportation; sewage or solid waste disposal facilities; or air and water pollution
                          control projects.

                          Each Fund will limit its investment in securities whose issuers are located in the same state to less
                          than 25% of the Fund's total assets.

                          Each Fund may invest up to 25% of its total assets in the "first tier securities" of a single issuer for
                          up to three business days after purchase. First tier securities are securities (1) rated in the highest
                          short-term category by two nationally recognized statistical rating organizations (NRSROs); (2) rated in
                          the highest short-term rating category by a single NRSRO if only that NRSRO has assigned the securities a
                          short-term rating; or (3) unrated, but determined by SAM to be of comparable quality.

                          Each Fund may invest in any of the following types of short-term, tax-exempt obligations: municipal notes
                          of issuers rated, at the time of purchase, within one of the three highest grades assigned by a NRSRO;
                          unrated municipal notes offered by issuers having outstanding municipal bonds rated within one of the
                          three highest grades assigned by an NRSRO; notes issued by or on behalf of municipal issuers that are
                          guaranteed by the U.S. government; tax-exempt commercial paper assigned one of the two highest grades by
                          an NRSRO; certificates of deposit issued by banks with assets of $1,000,000,000 or more; and municipal

                          Fund will not commit to additional securities purchases if total outstanding borrowings are equal to 5%
                          or more of total assets.

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:

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

(1) No sales load will apply to shares received in the Reorganization by
shareholders of your Fund who become shareholders of record of Pioneer TF Money
Market Fund through the Reorganization. In addition, shareholders of your 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 TF 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 TF
Money Market Fund to the extent the Fund's total ordinary operating expenses
exceeded 0.30% of the Fund's average daily net asset value in a fiscal year.
This arrangement included all Fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses.

(3) Pioneer has agreed that through the second anniversary of the closing of the
Reorganization, Pioneer will limit the ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Investor Class
shares of Pioneer TF 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 Fund.

(6) A contingent deferred sales charge may apply if you redeem Class B shares of
your 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.

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 TF Money
Market Fund and two years for Pioneer TF Money Market Fund and (f) and the
Investor Class shares of Pioneer TF 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 TF Money Market Fund. The Trustees considered the following matters,
among others, in approving the proposal.


                                        6


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 Fund's investment management 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 by UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your 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 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 many other money market and tax free
portfolios. At June 30, 2004, Pioneer managed portfolios investing in tax exempt
securities with aggregate assets of $__ billion and money market portfolios with
assets of $__ million.

Fourth, Pioneer and its affiliates have greater potential for increasing the
size of your Fund due to Pioneer's experience in distributing mutual funds
through a broader range of distribution channels than currently available to
your 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 ordinary operating expenses (excluding taxes, commissions, interest
and extraordinary expenses) of the Investor Class of Pioneer TF Money Market
Fund to 0.67% 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 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) 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 TF Money Market Fund received in
the Reorganization will provide Safeco TF 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 TF Money Market Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer TF 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 TF Money Market Fund
and its shareholders.

Capitalization

The following table sets forth the capitalization of each Fund, as of December
31, 2003.

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

The Trustees recommend that the shareholders of your 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 as of 4:00 p.m., Eastern time, on
     [   ], 2004, unless your Safeco Fund and the corresponding Pioneer Fund
     agree in writing to a later date. Each 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 assets value at the closing of the
     Reorganization. The net asset value of both Funds will be computed as of
     4:00 p.m., Eastern time, on the closing date of the Reorganization.

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 Reorganization 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 not intended to result in 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 (the "Plan"), the form of which is attached as EXHIBIT A.
The description of the Plan contained herein is qualified in its entirety by the
attached copy.

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, attached as
EXHIBIT A).

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, attached as EXHIBIT A).

TERMINATION OF AGREEMENT. The board of either a Safeco Fund 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 not intended to result in 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;

                                       10


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.

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 transaction, including the applicability of any state, local or foreign
tax laws.

                               PROPOSALS 17(a)-(p)
            APPROVAL OF APPOINTMENT OF PIONEER AS INVESTMENT ADVISER

BACKGROUND

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

Your approval of Pioneer will constitute approval of an interim advisory
agreement between your Safeco Fund and Pioneer. In the event that the interim
advisory contract is approved but the Reorganization is not approved, the
interim advisory contract would continue in effect for an indefinite period. The
fee under the interim agreement is the same as the fee under the current
advisory agreement.

INTERIM ADVISORY AGREEMENT

Under the Investment Company Act, shareholders must approve any new investment
adviser to 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 approval of the new adviser is submitted
to shareholders within 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 advisory agreement will be held
in escrow until shareholders approval is obtained. If Pioneer is not approved as
investment adviser to a Fund, 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 Fund. During this period prior to the
meeting, the Funds would 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 [   ], 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. If both the Reorganization and appointment of Pioneer
are approved, the interim agreement will continue in effect until the closing of
the Reorganization, even if that occurs after December [   ], 2004.

The interim agreement incorporates the terms of the existing advisory agreements
with SAM, which are discussed below. The form of interim agreement is attached
as Exhibit B.

SAFECO ADVISORY AGREEMENT

The following is a summary of the material terms of the Funds' existing
investment advisory agreement with SAM (the "Safeco Advisory Agreement").

SERVICES. Under the terms of the Safeco Advisory Agreement, SAM manages the
Funds' investments, subject to the supervision of the board of trustees. At its
expense, SAM provides office space and all necessary office facilities,
equipment and personnel for managing the investments of the Funds.

COMPENSATION. As compensation under the Safeco Advisory Agreement, each Safeco
Fund pays SAM a monthly advisory fee at an annual rate as listed in the below
table of the Fund's average daily net assets. In addition, SAM has agreed to
reimburse each Fund to the extent a Fund's total annual expenses, other than
taxes, interest and extraordinary litigation 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 includes all Fund operating expenses except management fees,
Rule 12b-1 fees, brokerage commissions, taxes, interest, and extraordinary
expenses. This limitation cannot be changed without shareholder approval.
Brokers' commissions and other charges relative to the purchase and sale of
portfolio securities are not regarded as expenses.

of your Safeco Fund's average daily net assets up to the first $200,000,000 and
0.01% of its net assets thereafter, and an accounting fee of 0.04% of the Fund's

duties under the agreement.

TERMINATION, CONTINUANCE AND AMENDMENT. The Safeco Advisory Agreement continues
from year to year subject to approval of its continuance at least annually by
the vote of (1) a majority of your Safeco Fund's independent trustees, in each
case cast in person at a meeting called for the purpose of voting on such
approval or (2) a majority of the outstanding voting securities (as that phrase
is defined in Section 2(a)(42) of the Investment Company Act) of each Fund. The

                         VOTING RIGHTS AND REQUIRED VOTE

Each share of your Safeco Fund is entitled to one vote and each fractional share
shall be entitled to a proportionate fractional vote. A quorum is required to
conduct business at the Meeting. With respect to each Safeco Fund, the presence

the Meeting will constitute a quorum. A favorable vote of a "majority of the
outstanding voting securities" of the applicable Fund is required to approve
each Proposal. Under the Investment company Act, majority of the outstanding
voting securities means the affirmative vote of the lesser of (i) 50% or more of

                 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 and
determining whether to approve and renew the fund's investment management
agreement and the sub-advisory 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

                                       15


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 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.

The Pioneer International Equity Fund primarily invests in securities of
non-U.S. issuers and the markets for these securities generally close prior to
the time the fund determines its net asset value. However, the value of these
securities continues to be influenced by changes in the global markets.
Consequently, the 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) 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.

account options forms and other account information:

TELEPHONE TRANSACTION PRIVILEGES. If your account is registered in your name,
you can buy, exchange or sell shares of the Pioneer Funds by telephone. If you
do not want your account to have telephone transaction privileges, you must
indicate that choice on your account application or by writing to the transfer
agent.

When you request a telephone transaction the transfer agent will try to confirm
that the request is genuine. The transfer agent records the call, requires the
caller to provide the personal identification number for the account and sends
you a written confirmation. Each Pioneer Fund may implement other confirmation
procedures from time to time. Different procedures may apply if you have a
non-U.S. account or if your account is registered in the name of an institution,
broker-dealer or other third party.

ONLINE TRANSACTION PRIVILEGES. If your account is registered in your name, you
may be able to buy, exchange or sell fund shares online. Your investment firm
may also be able to buy, exchange or sell your Safeco 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.

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. You 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 Internal Revenue Code. While financial
intermediaries that maintain omnibus accounts that invest in the fund are
requested to apply the exchange limitation policy to shareholders who hold
shares through such accounts, we do not impose the exchange limitation policy at
the level of the omnibus account and are not able to monitor compliance by the
financial intermediary with this policy.

REDEMPTION FEE. Pioneer International Equity Fund has adopted a redemption fee
on short term holdings of the fund's shares. If you sell or exchange shares
within 30 days of any purchase of fund shares, the fund will apply a 2% fee to
the entire amount of your sales proceeds. The fund's redemption fee is intended
to discourage short-term trading in fund shares. Short-term trading can increase
the expenses incurred by the fund and make portfolio management less efficient.

                                       20


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.

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 for the fund to sell or value its
portfolio securities or with the permission of the Securities and Exchange
Commission.

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.

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.

                                       21


Short-term capital gain distributions are taxable as ordinary income. Dividends
(other than exempt-interest dividends) are taxable either as ordinary income or,
if so designated by the fund and certain other conditions, including holding
period requirements, are met by the fund and the shareholder, as "qualified
dividend income" taxable to individual shareholders at the maximum 15% U.S.
federal tax rate. Dividends and distributions generally are taxable, whether you
take payment in cash or reinvest them to buy additional Pioneer Fund shares.

When you sell or exchange Pioneer Fund shares you will generally recognize a
capital gain or capital loss in an amount equal to the difference between the
net amount of sale proceeds (or, in the case of an exchange, the fair market
value of the shares) that you receive and your tax basis for the shares that you
sell or exchange. In January of each year each Pioneer Fund will mail to you
information about your dividends, distributions and any shares you sold in the
previous calendar year.

You must provide your social security number or other taxpayer identification
number to the fund along with the certifications required by the Internal
Revenue Service when you open an account. If you do not or if it is otherwise
legally required to do so, the Pioneer Fund will withhold 28% "backup
withholding" tax from your dividends and distributions, sale proceeds and any
other payments to you.

You should ask your tax adviser about any federal, state and foreign tax
considerations, including possible additional withholding taxes for non-U.S.
shareholders. You may also consult the "Tax Status" section of each Pioneer
Fund's statement of additional information for a more detailed discussion of
U.S. federal income tax considerations, including qualified dividend income
considerations that may affect the Pioneer Fund and its shareowners.

                     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 1940 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 semi-annual 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 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 was audited by Arthur Anderson LLP.
The information for any semi-annual period has not been audited.

(a)  At January 1, 2001, the Fund 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 less than one
     cent per share, increase net realized and unrealized gain (loss) by less
     than one cent per share and decrease the ratio of net investment income to
     average net assets assuming reduction for fees paid indirectly from 2.02%
     to 1.98%. Per share ratios and supplemental data for periods prior to
     January 1, 2002, have not been restated to reflect this change in
     presentation.

(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
     indirectly from 5.35% to 5.15%. Per share ratios and supplemental data for
     periods prior to January 1, 2001, have not been restated to reflect this
     change in presentation.

                       INFORMATION CONCERNING THE MEETING

SOLICITATION OF PROXIES

In addition to the mailing of these proxy materials, proxies may be solicited by
telephone, by fax or in person by the trustees, officers and employees of your
Safeco Fund; by personnel of your Safeco Fund, Pioneer Funds' investment
adviser, Pioneer, their transfer agent, PIMSS, or by broker-dealer firms. [ ]
has been retained to provide proxy solicitation services to the Funds at a cost
of approximately $[_____]. Pioneer and Symetra will bear the cost of such
solicitation.

REVOKING PROXIES

A Safeco Fund shareholder signing and returning a proxy has the power to revoke
it at any time before it is exercised:

o    by filing a written notice of revocation with your Safeco Fund's transfer
     agent, Safeco Services Corporation, at [ ], or

o    by returning a duly executed proxy with a later date before the time of the
     Meeting, or

o    if a shareholder has executed a proxy but is present at the Meeting and
     wishes to vote in person, by notifying the secretary of your Safeco Fund
     (without complying with any formalities) at any time before it is voted.

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

OUTSTANDING SHARES AND QUORUM

Only shareholders of record on [ ], 2004 (the "record date") are entitled to
notice of and to vote at the Meetings. The presence in person or by proxy by
one-third of the outstanding shares entitled to cast votes at the Meeting will
constitute a quorum.

As of the record date,  the following  number of shares of each Safeco Fund were
outstanding.

OTHER BUSINESS

Your Fund's board of trustees knows of no business to be presented for
consideration at the Meetings other than Proposals 1-17. If other business is
properly brought before a Meeting, proxies will be voted according to the best
judgment of the persons named as proxies.

                                       35


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 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 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.]

                                       36


SHAREHOLDERS' PROPOSALS

Your 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 at [ ] 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 subject to deferred sales charges (if any).

                        OWNERSHIP OF SHARES OF THE FUNDS

To the knowledge of your Safeco Fund, as of [ ], 2004, the following persons
owned of record or beneficially 5% or more of the outstanding shares of each of
the Safeco Funds.

such Acquired Fund Shareholder on the Closing Date. Such liquidation and
distribution will be accomplished by the Safeco Trust instructing the Acquiring
Fund to transfer the Acquiring Fund Shares then credited to the account of the
Acquired Fund on the books of the Acquiring Fund to open accounts on the share
records of the Acquiring Fund established and maintained by the Acquiring Fund's
transfer agent in the names of the Acquired Fund Shareholders and representing
the respective pro rata number of the Acquiring Fund Shares due the Acquired
Fund Shareholders. The 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. The Acquired Fund
Shareholders holding certificates representing their ownership of Acquired Fund
Shares shall surrender such certificates or deliver an affidavit with respect to
lost certificates in such form and accompanied by such surety bonds as the
Acquired Fund may require (collectively, an "AFFIDAVIT"), to Pioneer Investment
Management Shareholder Services, Inc. prior to the Closing Date. Any Acquired
Fund Share certificate that remains outstanding on the Closing Date shall be
deemed to be cancelled, shall no longer evidence ownership of the Acquired Fund
Shares, but shall evidence ownership of Acquiring Fund Shares as determined in
accordance with Paragraph 1.4. Unless and until any such certificate shall be so
surrendered or an Affidavit relating thereto shall be delivered by an Acquired
Fund Shareholder, dividends and other distributions payable by the Acquiring
Fund subsequent to the Liquidation Date with respect to Acquiring Fund Shares
shall be paid to such Acquired Fund Shareholder, but such Acquired Fund
Shareholder may not redeem or transfer Acquiring Fund Shares received in the
Reorganization. 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 (as computed below) 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;
provided, however, if the Acquiring Fund has no assets as of the Closing Date
(other than a nominal amount of assets attributable to the shares issued to the
Acquiring Fund Adviser, or its affiliate, as the initial shareholder of the
Acquiring Fund), the NAV of each Acquiring Fund Share shall be the same as the
NAV of each share of the Acquired Fund. The NAV of the Acquired Assets 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

                                       40


the liabilities of the Acquired Fund on the Closing Date included on the face of
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 the NAV of the Acquired Assets.

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 , 2004, or such later date as the parties may
agree to in writing. All acts necessary to consummation the Reorganizations (the
"CLOSING") shall be deemed to take place simultaneously as of 5:00 p.m. (Eastern
time) on the Closing Date unless otherwise provided. The Closing shall be held
at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street,
Boston, Massachusetts, or at such other place as the parties may agree.

3.2 Portfolio securities that are held other than in book-entry form in the name
of 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. Portfolio securities
which are not held in book-entry form 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 transfer of beneficial ownership thereof to 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 In the event that 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 Assets
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 such 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 party to or subject to the provisions of any
     order, decree or judgment of any court or governmental body which
     materially adversely affects the Acquired Fund's business or its ability to
     consummate the transactions contemplated herein or would be binding upon
     the Acquiring Fund as the successor to the Acquired Fund;

(e)  The Acquired Fund has no material contracts or other commitments (other
     than this Agreement or agreements for the purchase and sale of securities
     entered into in the ordinary course of business and consistent with its
     obligations under this Agreement) which will not be terminated at or prior
     to the Closing Date and no such termination will result in liability to the
     Acquired Fund (or the Acquiring Fund);

(f)  The statement of assets and liabilities of the Acquired Fund, and the
     related statements of operations and changes in net assets as of and for
     the most recent fiscal year have been audited by Ernst & Young LLP,
     independent registered public accounting firm, and are in accordance with
     U.S. 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. 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 [most recent fiscal year end], except as specifically disclosed in
     the Acquired Fund's prospectus, its statement of additional information as
     in effect on the date of this Agreement, or in its semi-annual report for
     the period ended [ ], 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 will meet, the
     requirements of Subchapter M of the Code for qualification. The Acquired
     Fund has elected to be treated as such 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,

                                       42


     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. 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;

                                       43


     (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,

     or foreign government, or any agency thereof, or other political
     subdivision of the United States or any such government, 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.

     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;

     for use in applications for orders, registration statements, proxy
     materials and other documents which may be necessary in connection with the

     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")

     The Acquiring Fund is not required to qualify to do business in any

     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

                        TAX REPRESENTATION CERTIFICATE OF

                                 [SAFECO TRUST]
                           ON BEHALF OF [SAFECO FUND]

This certificate is being delivered in connection with the transaction to be
effected pursuant to the Agreement and Plan of Reorganization made as of , 2004
between [Pioneer Trust], a Delaware statutory Trust on behalf of its series,
[Pioneer Fund] ("Acquiring Fund") and [Safeco Trust]., a Delaware statutory
trust ("SAFECO TRUST"), on behalf of [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 liabilities of Acquired Fund (the "Acquired Fund Liabilities") and
(ii) the issuance of shares of beneficial interest of Acquiring Fund (the
"Acquiring Fund Shares") to Acquired Fund, followed by the distribution by
Acquired Fund, in liquidation of Acquired Fund, of the Acquiring Fund Shares to
the shareholders of Acquired Fund and the termination of Acquired Fund (the
foregoing together constituting the "transaction").

The undersigned officer of the 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 meaning ascribed to them in the Agreement.

1. Acquired Fund is a series of the 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 income 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 the 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 shareholders of Acquired Fund to engage
in any transaction with Acquired Fund, the 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 and Assumed
Liabilities to Acquiring Fund such that immediately following the transfer,

any liabilities not included in Assumed 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 in exchange for the assets of Acquired Fund
will be approximately equal to the fair market value of the assets of Acquired
Fund received by Acquiring Fund, minus the Assumed Liabilities. Acquired Fund
will not receive any consideration from Acquiring Fund in connection with the
acquisition of Acquired Fund's assets other than the assumption of such Assumed
Liabilities and the issuance of such Acquiring Fund Shares.

                                       57


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 Acquired Fund Liabilities
assumed by the Acquiring Fund.

7. As or the Closing Date, the adjusted basis and the fair market value of the
Acquired Fund assets transferred to Acquiring Fund will equal or exceed the
Assumed Liabilities within the meaning of Section 357(d) of the Internal Revenue
Code of 1986, as amended (the "Code").

8. Acquired Fund currently conducts its historic business within the meaning of
Treasury Regulation section 1.368-1(d)(2), which provides that, in general, a
corporation's historic business is the business it has conducted most recently,
but does not include a business that the corporation enters into as part of a
plan of reorganization. The Acquired Fund assets transferred to Acquiring Fund
will be Acquired Fund's historic business assets within the meaning of Treasury
Regulation section 1.368-1(d)(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, and its other properties, if any, pursuant to the transaction and
will be liquidated promptly thereafter.

10. The expenses of Acquired Fund incurred by it in connection with the
transaction which are to be assumed by Acquiring Fund, 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 treated as 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 as such as of the time of
the Closing on the Closing Date.

Section 368(a)(2)(F) of the Code.

14. Acquired Fund is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

15. Acquired Fund does not pay compensation to any shareholder-employee.

all of the outstanding Acquiring Fund Shares issued to Acquired Fund pursuant to
the transaction and will own such shares solely by reason of their ownership of
the Acquired Fund Shares immediately prior to the transaction.

17. Acquired Fund shareholders will not have dissenters' or appraisal rights in
the transaction.

18. The transaction is being undertaken for valid and substantial business
purposes, including facilitating the Acquired Fund 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.

19. Acquired Fund has no outstanding warrants, options, convertible securities
or any other type of right pursuant to which any person could acquire stock in

ANNEX 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 advisor 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.

     In witness whereof, the parties hereto have executed this Agreement as
the2ndt day of August 2004.

ANNEX C - ADDITIONAL INFORMATION PERTAINING TO PIONEER

OWNERSHIP OF PIONEER. Pioneer is an indirect, wholly owned subsidiary of
UniCredito Italiano.

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.

Registration Statement by any person or party which is deemed to be an
underwriter within the meaning of Rule 145(c) of the Securities Act of 1933, the
reoffering prospectus will contain the information called for by the applicable
registration form for the reofferings by persons who may be deemed underwriters,
in addition to the information called for by the other items of the applicable
form.

(2) The undersigned Registrant agrees that every prospectus that is filed under
paragraph (1) above will be filed as part of an amendment to the Registration
Statement and will not be used until the amendment is effective, and that, in
determining any liability under the Securities Act of 1933, each post-effective
amendment shall be deemed to be a new registration statement for the securities
offered therein, and the offering of the securities at that time shall be deemed
to be the initial bona fide offering of them.
