                                  FUND HISTORY

The fund is a diversified, closed-end management investment company organized as
a Delaware statutory trust on January 30, 2007.

                                 USE OF PROCEEDS

The net proceeds will be invested in accordance with the fund's investment
objectives and policies during a period not to exceed three months from the
closing of this offering. Pending such investment, the net proceeds may be
invested in U.S. government securities or high grade, short-term money market
instruments. If necessary, the fund may also purchase, as temporary investments,
securities of other open-end and closed-end investment companies that invest in
equity and fixed-income securities.

                       INVESTMENT OBJECTIVES AND POLICIES

The prospectus presents the investment objectives and the principal investment
strategies and risks of the fund. This section supplements the disclosure in the
fund's prospectus and provides additional information on the fund's investment
policies or restrictions. Restrictions or policies stated as a maximum
percentage of the fund's assets are only applied immediately after a portfolio
investment to which the policy or restriction is applicable (other than the
limitations on borrowing). Accordingly, any later increase or decrease resulting
from a change in values, net assets or other circumstances will not be
considered in determining whether the investment complies with the fund's
restrictions and policies.

EVENT-LINKED BONDS

Event-linked bonds are debt obligations for which the return of principal and
the payment of interest are contingent on the non-occurrence of a pre-defined
"trigger" event, such as a hurricane or an earthquake of a specific magnitude.
If a trigger event causes losses exceeding a specific amount or magnitude in the
geographic region and time period specified in a bond, the fund may lose a
portion or all of its accrued interest and/or principal invested in the bond. If
no trigger event occurs, the fund is entitled to recover its principal plus
accrued interest.

The fund's investments in event-linked bonds may be linked to a broad range of
insurance risks, which can be broken down into three major categories: natural
risks, weather risks and non-natural events. Investments in event-linked bonds
linked to natural risks represent the largest portion of the fund's event-linked
bond investments. The events covered are natural catastrophes, such as
hurricanes and earthquakes. Investments in event-linked bonds linked to weather
risks provide insurance to companies whose sales depend on the weather and
provide a hedge on the impact of weather-related risks. For example, a weather
event-linked bond could provide coverage based on the average temperature in a
region over a given period. Investments in event-linked bonds linked to
non-natural risks could cover a much broader array of insurable risks, such as
aerospace and shipping catastrophes.

The fund may invest in other types of event-linked bonds where the trigger event
or magnitude of losses may be based on company-wide losses, index-based losses
or a combination of triggers.

Event-linked bonds are typically rated by at least one nationally recognized
rating agency, primarily Standard & Poor's Ratings Group ("Standard & Poors"),
Fitch Ratings, Ltd. ("Fitch"), and/or A.M. Best Company, Inc. ("A.M. Best").
Although each rating agency utilizes its own general guidelines and methodology
to evaluate the risks of an event-linked bond, the average rating in the current
market for event-linked bonds is "BB" by Standard & Poors (or the equivalent
rating for another rating agency). However, there are event-linked bonds rated
higher or lower than "BB." Montpelier Capital Advisors,


                                       2



Ltd., the fund's investment subadviser ("Montpelier" or "Subadviser"),
anticipates that the fund's investments in event-linked bonds generally will be
rated B, BB or BBB at the time of purchase, although the fund may invest in
event-linked bonds rated higher or lower than these ratings, as well as
event-linked bonds that are unrated. The rating for an event-linked bond
primarily reflects the rating agency's calculated probability that a pre-defined
trigger event will occur, rather than the bond's credit risk. This rating also
assesses the model used to calculate the probability of the trigger event. There
currently are three primary independent catastrophe-modeling firms (EQECAT,
Inc., AIR Worldwide Corp and Risk Management Solutions, Inc.), which utilize
different methodologies to evaluate the probability of various types of
pre-defined trigger events. For event-linked bonds with a "BB" rating, the
average expected loss probability is approximately 1% (i.e., loss occurrence
once every 100 years).

FLOATING RATE LOANS

A floating rate loan is typically originated, negotiated and structured by a
U.S. or foreign commercial bank, insurance company, finance company or other
financial institution for a group of investors. The financial institution
typically acts as an agent for the investors, administering and enforcing the
loan on their behalf. In addition, an institution, typically but not always the
agent, holds any collateral on behalf of the investors.

The interest rates are adjusted based on a base rate plus a premium or spread
over the base rate. The base rate usually is the London Interbank Offer Rate
("LIBOR"), the Federal Reserve federal funds rate, the prime rate or other base
lending rates used by commercial lenders. LIBOR usually is an average of the
interest rates quoted by several designated banks as the rates at which they pay
interest to major depositors in the London interbank market on U.S.
dollar-denominated deposits.

Floating rate loans include loans to corporations and institutionally traded
floating rate debt obligations issued by an asset-backed pool, and interests
therein. In addition to term loans, loans may include revolving credit
facilities, prefunded letter of credit term loans, delayed draw term loans and
receivables purchase facilities. The fund may invest in loans in different ways.
The fund may: (i) make a direct investment in a loan by participating as one of
the lenders; (ii) purchase a participation interest in a loan; or (iii) purchase
an assignment of a loan.

DIRECT INVESTMENT IN LOANS. It can be advantageous to the fund to make a direct
investment in a loan as one of the lenders. When a new issue is purchased, such
an investment is typically made at par. This means that the fund receives a
return at the full interest rate for the loan. Secondary purchases of loans may
be made at par, at a premium from par or at a discount from par. When the fund
invests in an assignment of, or a participation interest in, a loan, the fund
may pay a fee or forgo a portion of the interest payment. Consequently, the
fund's return on such an investment may be lower than it would have been if the
fund had made a direct investment in the underlying corporate loan. The fund may
be able, however, to invest in corporate loans only through assignments or
participation interests at certain times when reduced direct investment
opportunities in corporate loans may exist.

ASSIGNMENTS. An assignment represents a portion of a loan previously
attributable to a different lender. The purchaser of an assignment typically
succeeds to all the rights and obligations under the loan agreement of the
assigning investor and becomes an investor under the loan agreement with the
same rights and obligations as the assigning investor. Assignments may, however,
be arranged through private negotiations between potential assignees and
potential assignors, and the rights and obligations acquired by the purchaser of
an Assignment may differ from, and be more limited than, those held by the
assigning investor.


                                       3



PARTICIPATION INTERESTS. Participation interests are interests issued by a
lender or other financial institution, which represent a fractional interest in
a corporate loan. The fund may acquire participation interests from the
financial institution or from another investor. The fund typically will have a
contractual relationship only with the financial institution that issued the
participation interest. As a result, the fund may have the right to receive
payments of principal, interest and any fees to which it is entitled only from
the financial institution and only upon receipt by such entity of such payments
from the borrower. In connection with purchasing a participation interest, the
fund generally will have no right to enforce compliance by the borrower with the
terms of the loan agreement, nor any rights with respect to any funds acquired
by other investors through set-off against the borrower and the fund may not
directly benefit from the collateral supporting the loan in which it has
purchased the participation interest. As a result, the fund may assume the
credit risk of both the borrower and the financial institution issuing the
participation interest. In the event of the insolvency of the financial
institution issuing a participation interest, the fund may be treated as a
general creditor of such entity.

OTHER INFORMATION ABOUT FLOATING RATE LOANS. Loans typically have a senior
position in a borrower's capital structure. The capital structure of a borrower
may include loans, senior unsecured loans, senior and junior subordinated debt,
preferred stock and common stock, typically in descending order of seniority
with respect to claims on the borrower's assets. Although loans typically have
the most senior position in a borrower's capital structure, they remain subject
to the risk of non-payment of scheduled interest or principal. Such non-payment
would result in a reduction of income to the fund, a reduction in the value of
the investment and a potential decrease in the net asset value of the fund.
There can be no assurance that the liquidation of any collateral securing a loan
would satisfy a borrower's obligation in the event of non-payment of scheduled
interest or principal payments, or that such collateral could be readily
liquidated. In the event of bankruptcy of a borrower, the fund could experience
delays or limitations with respect to its ability to realize the benefits of the
collateral securing a loan. Although a loan may be senior to equity and other
debt securities in an issuer's capital structure, such obligations may be
structurally subordinated to obligations of the issuer's subsidiaries. For
example, if a holding company were to issue a loan, even if that issuer pledges
the capital stock of its subsidiaries to secure the obligations under the loan,
the assets of the operating companies are available to the direct creditors of
an operating company before they would be available to the holders of the loan
issued by the holding company.

In order to borrow money pursuant to a loan, a borrower will frequently, for the
term of the loan, pledge collateral, including but not limited to, (i) working
capital assets, such as accounts receivable and inventory; (ii) tangible fixed
assets, such as real property, buildings and equipment; (iii) intangible assets,
such as trademarks and patent rights (but excluding goodwill); and (iv) security
interests in shares of stock of subsidiaries or affiliates. In the case of loans
made to non-public companies, the company's shareholders or owners may provide
collateral in the form of secured guarantees and/or security interests in assets
that they own. In many instances, a loan may be secured only by stock in the
borrower or its subsidiaries. Collateral may consist of assets that may not be
readily liquidated, and there is no assurance that the liquidation of such
assets would satisfy fully a borrower's obligations under a loan.

The fund may invest in loans that are second in lien priority rather than first.
Accordingly, the risks associated with "second lien" loans are higher than the
risk of loans with first priority over the collateral. In the event of default
on a "second lien" loan, the first priority lien holder has first claim to the
underlying collateral of the loan. It is possible that no collateral value would
remain for the second priority lien holder and would therefore result in a loss
of investment to the fund.

In the process of buying, selling and holding loans, the fund may receive and/or
pay certain fees. Any fees received are in addition to interest payments
received and may include facility fees, commitment fees, commissions and
prepayment penalty fees. When the fund buys a loan it may receive a facility fee
and when it sells a loan it may pay a facility fee. On an ongoing basis, the
fund may receive a commitment fee


                                       4



based on the undrawn portion of the underlying line of credit portion of a loan.
In certain circumstances, the fund may receive a prepayment penalty fee upon the
prepayment of a loan by a borrower. Other fees received by the fund may include
covenant waiver fees and covenant modification fees.

A borrower must comply with various restrictive covenants contained in a loan
agreement or note purchase agreement between the borrower and the holders of the
loan. Such covenants, in addition to requiring the scheduled payment of interest
and principal, may include restrictions on dividend payments and other
distributions to stockholders, provisions requiring the borrower to maintain
specific minimum financial ratios, and limits on total debt.

In a typical loan, the agent administers the terms of the loan agreement. In
such cases, the agent is normally responsible for the collection of principal
and interest payments from the borrower and the apportionment of these payments
to the credit of all institutions that are parties to the loan agreement. The
fund will generally rely upon the agent or an intermediate participant to
receive and forward to the fund its portion of the principal and interest
payments on the loan. Furthermore, unless the fund has direct recourse against
the borrower, the fund will rely on the agent and the other investors to use
appropriate credit remedies against the borrower.

For some loans, such as revolving credit facility loans ("revolvers"), an
investor may have certain obligations pursuant to the loan agreement that may
include the obligation to make additional loans in certain circumstances. The
fund generally will reserve against these contingent obligations by segregating
or otherwise designating a sufficient amount of permissible liquid assets.
Delayed draw term loans are similar to revolvers, except that once drawn upon by
the borrower during the commitment period, they remain permanently drawn and
become term loans. A prefunded L/C term loan is a facility created by the
borrower in conjunction with an agent, with the loan backed by letters of
credit. Each participant in a prefunded L/C term loan fully funds its commitment
amount to the agent for the facility.

The fund may acquire interests in loans that are designed to provide temporary
or "bridge" financing to a borrower pending the sale of identified assets or the
arrangement of longer-term loans or the issuance and sale of debt obligations.
Bridge loans often are unrated. The fund may also may invest in loans of
borrowers that have obtained bridge loans from other parties. A borrower's use
of bridge loans involves a risk that the borrower may be unable to locate
permanent financing to replace the bridge loan, which may impair the borrower's
perceived creditworthiness.

From time to time, Pioneer Investment Management, Inc., the fund's investment
adviser ("Pioneer"), and its affiliates may borrow money from various banks in
connection with their business activities. Such banks may also sell interests in
loans to or acquire them from the fund or may be intermediate participants with
respect to loans in which the fund owns interests. Such banks may also act as
agents for loans held by the fund.

DEBTOR-IN-POSSESSION FINANCING


The fund may invest in debtor-in-possession financings (commonly called "DIP
financings"). DIP financings are arranged when an entity seeks the protections
of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code. These
financings allow the entity to continue its business operations while
reorganizing under Chapter 11. Such financings are senior liens on unencumbered
security (i.e., security not subject to other creditors' claims). There is a
risk that the entity will not emerge from Chapter 11 and would be forced to
liquidate its assets under Chapter 7 of the Bankruptcy Code. In such event, the
fund's only recourse will be against the property securing the DIP financing,
which amount realized may be substantially less than the amount owed on the DIP
financing.



                                       5



INVERSE FLOATING RATE SECURITIES

The interest on an inverse floater resets in the opposite direction from the
market rate of interest to which the inverse floater is indexed. An inverse
floater may be considered to be leveraged to the extent that its interest rate
varies by a magnitude that exceeds the magnitude of the change in the index rate
of interest. The higher degree of leverage inherent in inverse floaters is
associated with greater volatility in their market values.

DEBT SECURITIES RATING CRITERIA

Investment grade debt securities are those rated "BBB" or higher by Standard &
Poor's or the equivalent rating of other nationally recognized statistical
rating organizations. Debt securities rated BBB are considered medium grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken the issuer's ability to pay interest and repay
principal.


Below investment grade debt securities are those rated "BB" and below by
Standard & Poor's or the equivalent rating of other nationally recognized
statistical rating organizations. See "Appendix A" for a description of rating
categories.


Below investment grade debt securities or comparable unrated securities are
commonly referred to as "junk bonds" and are considered predominantly
speculative and may be questionable as to principal and interest payments.
Changes in economic conditions are more likely to lead to a weakened capacity to
make principal payments and interest payments. The amount of high yield
securities outstanding has proliferated as an increasing number of issuers have
used high yield securities for corporate financing. An economic downturn could
severely affect the ability of highly leveraged issuers to service their debt
obligations or to repay their obligations upon maturity. Factors having an
adverse impact on the market value of lower quality securities will have an
adverse effect on the fund's net asset value to the extent that it invests in
such securities. In addition, the fund may incur additional expenses to the
extent it is required to seek recovery upon a default in payment of principal or
interest on its portfolio holdings.

The secondary market for high yield securities may not be as liquid as the
secondary market for more highly rated securities, a factor which may have an
adverse effect on the fund's ability to dispose of a particular security when
necessary to meet its liquidity needs. Under adverse market or economic
conditions, the secondary market for high yield securities could contract
further, independent of any specific adverse changes in the condition of a
particular issuer. As a result, the fund could find it more difficult to sell
these securities or may be able to sell the securities only at prices lower than
if such securities were widely traded. Prices realized upon the sale of such
lower rated or unrated securities, under these circumstances, may be less than
the prices used in calculating the fund's net asset value.

Since investors generally perceive that there are greater risks associated with
lower quality debt securities of the type in which the fund may invest a portion
of its assets, the yields and prices of such securities may tend to fluctuate
more than those for higher rated securities. In the lower quality segments of
the debt securities market, changes in perceptions of issuers' creditworthiness
tend to occur more frequently and in a more pronounced manner than do changes in
higher quality segments of the debt securities market, resulting in greater
yield and price volatility.

Lower rated and comparable unrated debt securities tend to offer higher yields
than higher rated securities with the same maturities because the historical
financial condition of the issuers of such securities may not have been as
strong as that of other issuers. However, lower rated securities generally
involve greater risks of loss of income and principal than higher rated
securities. Pioneer will attempt to reduce these


                                       6



risks through portfolio diversification and by analysis of each issuer and its
ability to make timely payments of income and principal, as well as broad
economic trends and corporate developments.

For purposes of the fund's credit quality policies, if a security receives
different ratings from nationally recognized statistical rating organizations,
the fund will use the rating chosen by the portfolio manager as most
representative of the security's credit quality. If a rating organization
changes the quality rating assigned to one or more of the fund's portfolio
securities, Pioneer will consider what actions, if any, are appropriate
including selling the security or purchasing additional securities of the
appropriate credit quality as soon as it is prudent to do so.

FIXED-INCOME SECURITIES

In addition to corporate debt securities, which include corporate bonds,
debentures and notes, fixed-income securities also include preferred, preference
and convertible securities, equipment lease certificates, equipment trust
certificates and conditional sales contracts. Preference stocks are stocks that
have many characteristics of preferred stocks, but are typically junior to an
existing class of preferred stocks. Equipment lease certificates are debt
obligations secured by leases on equipment (such as railroad cars, airplanes or
office equipment), with the issuer of the certificate being the owner and lessor
of the equipment. Equipment trust certificates are debt obligations secured by
an interest in property (such as railroad cars or airplanes), the title of which
is held by a trustee while the property is being used by the borrower.
Conditional sales contracts are agreements under which the seller of property
continues to hold title to the property until the purchase price is fully paid
or other conditions are met by the buyer.

Fixed-rate bonds may have a demand feature allowing the holder to redeem the
bonds at specified times. These bonds are more defensive than conventional
long-term bonds (protecting to some degree against a rise in interest rates)
while providing greater opportunity than comparable intermediate term bonds,
since they may be retained if interest rates decline. Acquiring these kinds of
bonds provides the contractual right to require the issuer of the bonds to
purchase the security at an agreed upon price, which right is contained in the
obligation itself rather than in a separate agreement or instrument. Since this
right is assignable only with the bond, it will not be assigned any separate
value. Floating or variable rate obligations may be acquired as short-term
investments pending longer-term investment of funds.

Certain securities may permit the issuer at its option to "call," or redeem, the
securities. If an issuer were to redeem securities during a time of declining
interest rates, the fund may not be able to reinvest the proceeds in securities
providing the same investment return as the securities redeemed.

The rate of interest on a corporate debt security may be fixed, floating or
variable, and may vary inversely with respect to a reference rate. The rate of
return or return of principal on some debt obligations may be linked or indexed
to the level of exchange rates between the U.S. dollar and a foreign currency or
currencies.

CONVERTIBLE DEBT SECURITIES

The fund may invest in convertible debt securities which are debt obligations
convertible at a stated exchange rate or formula into common stock or other
equity securities of or owned by the issuer. Convertible securities rank senior
to common stocks in an issuer's capital structure and consequently may be of
higher quality and entail less risk than the issuer's common stock. As with all
debt securities, the market values of convertible securities tend to increase
when interest rates decline and, conversely, tend to decline when interest rates
increase.


                                       7



PREFERRED SHARES

The fund may invest in preferred shares of beneficial interest of trust
instruments. Preferred shares are equity securities, but they have many
characteristics of fixed income securities, such as a fixed dividend payment
rate and/or a liquidity preference over the issuer's common shares. However,
because preferred shares are equity securities, they may be more susceptible to
risks traditionally associated with equity investments than the fund's fixed
income securities.

ZERO-COUPON BONDS, DEFERRED INTEREST BONDS AND PAYMENT-IN-KIND SECURITIES

Zero-coupon securities are debt obligations that do not entitle the holder to
any periodic payments of interest either for the entire life of the obligation
or for an initial period after the issuance of the obligations. While zero
coupon bonds do not require the periodic payment of interest, deferred interest
bonds provide for a period of delay before the regular payment of interest
begins. Payment-in-kind securities ("PIKs") pay dividends or interest in the
form of additional securities of the issuer, rather than in cash. To the extent
the fund invests in such instruments, they will not contribute to the fund's
primary goal of current income. Each of these instruments is typically issued
and traded at a deep discount from its face amount. The amount of the discount
varies depending on such factors as the time remaining until maturity of the
securities, prevailing interest rates, the liquidity of the security and the
perceived credit quality of the issuer. The market prices of zero-coupon bonds,
deferred interest bonds and PIKs generally are more volatile than the market
prices of debt instruments that pay interest currently and in cash and are
likely to respond to changes in interest rates to a greater degree than do other
types of securities having similar maturities and credit quality. In order to
satisfy a requirement for qualification as a "regulated investment company"
under the Internal Revenue Code of 1986, as amended (the "Code"), an investment
company, such as the fund, must distribute each year at least 90% of its net
investment income, including the original issue discount accrued on zero-coupon
bonds, deferred interest bonds and PIKs. Because the fund will not, on a current
basis, receive cash payments from the issuer of these securities in respect of
any accrued original issue discount, in some years the fund may have to
distribute cash obtained from selling other portfolio holdings of the fund. In
some circumstances, such sales might be necessary in order to satisfy cash
distribution requirements even though investment considerations might otherwise
make it undesirable for the fund to sell securities at such time. Under many
market conditions, investments in zero-coupon bonds, deferred interest bonds and
PIKs may be illiquid, making it difficult for the fund to dispose of them or
determine their current value.

SHORT-TERM INVESTMENTS


For temporary defensive or cash management purposes, the fund may invest in all
types of short-term investments including, but not limited to, corporate
commercial paper and other short-term commercial obligations issued by domestic
companies; obligations (including certificates of deposit, time deposits, demand
deposits and bankers' acceptances) of banks located in the U.S.; obligations
issued or guaranteed by the U.S. government or its agencies or
instrumentalities; and repurchase agreements. Although these investments
generally are rated investment grade or are determined by Pioneer to be of
equivalent credit quality, the fund also may invest in these investments if they
are rated below investment grade in accordance with its investment objectives,
policies and restrictions.


U.S. GOVERNMENT SECURITIES

U.S. government securities in which the fund invests include debt obligations of
varying maturities issued by the U.S. Treasury or issued or guaranteed by an
agency or instrumentality of the U.S. government, including the Federal Housing
Administration, Federal Financing Bank, Farmers Home Administration,
Export-Import Bank of the U.S., Small Business Administration, Government
National Mortgage


                                       8



Association ("GNMA"), General Services Administration, Central Bank for
Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks ("FHLBs"),
Federal Home Loan Mortgage Corporation ("FHLMC"), Federal National Mortgage
Association ("FNMA"), Maritime Administration, Tennessee Valley Authority,
District of Columbia Armory Board, Resolution Trust Corporation and various
institutions that previously were or currently are part of the Farm Credit
System (which has been undergoing reorganization since 1987). Some U.S.
government securities, such as U.S. Treasury bills, Treasury notes and Treasury
bonds, which differ only in their interest rates, maturities and times of
issuance, are supported by the full faith and credit of the United States.
Others are supported by: (i) the right of the issuer to borrow from the U.S.
Treasury, such as securities of the FHLBs; (ii) the discretionary authority of
the U.S. government to purchase the agency's obligations, such as securities of
the FNMA; or (iii) only the credit of the issuer. No assurance can be given that
the U.S. government will provide financial support in the future to U.S.
government agencies, authorities or instrumentalities that are not supported by
the full faith and credit of the United States. Securities guaranteed as to
principal and interest by the U.S. government, its agencies, authorities or
instrumentalities include: (i) securities for which the payment of principal and
interest is backed by an irrevocable letter of credit issued by the U.S.
government or any of its agencies, authorities or instrumentalities; and (ii)
participations in loans made to non-U.S. governments or other entities that are
so guaranteed. The secondary market for certain of these participations is
limited and, therefore, may be regarded as illiquid.

U.S. government securities may include zero coupon securities that may be
purchased when yields are attractive and/or to enhance portfolio liquidity. Zero
coupon U.S. government securities are debt obligations that are issued or
purchased at a significant discount from face value. The discount approximates
the total amount of interest the security will accrue and compound over the
period until maturity or the particular interest payment date at a rate of
interest reflecting the market rate of the security at the time of issuance.
Zero coupon U.S. government securities do not require the periodic payment of
interest. These investments benefit the issuer by mitigating its need for cash
to meet debt service, but generally require a higher rate of return to attract
investors who are willing to defer receipt of cash. These investments may
experience greater volatility in market value than U.S. government securities
that make regular payments of interest. The fund accrues income on these
investments for tax and accounting purposes, which is distributable to
shareholders and which, because no cash is received at the time of accrual, may
require the liquidation of other portfolio securities to satisfy the fund's
distribution obligations, in which case the fund will forgo the purchase of
additional income producing assets with these funds. Zero coupon U.S. government
securities include STRIPS (Separate Trading of Registered Interest and Principal
of Securities) and CUBES (Coupons Under Book-Entry Safekeeping), which are
issued by the U.S. Treasury as component parts of U.S. Treasury bonds and
represent scheduled interest and principal payments on the bonds.

DEBT OBLIGATIONS OF NON-U.S. GOVERNMENTS

The fund may invest in debt obligations of non-U.S. governments. An investment
in debt obligations of non-U.S. governments and their political subdivisions
(sovereign debt) involve special risks that are not present in corporate debt
obligations. The non-U.S. issuer of the sovereign debt or the non-U.S.
governmental authorities that control the repayment of the debt may be unable or
unwilling to repay principal or interest when due, and a fund may have limited
recourse in the event of a default. During periods of economic uncertainty, the
market prices of sovereign debt may be more volatile than prices of debt
obligations of U.S. issuers. In the past, certain non-U.S. countries have
encountered difficulties in servicing their debt obligations, withheld payments
of principal and interest and declared moratoria on the payment of principal and
interest on their sovereign debt.

A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign currency reserves, the


                                       9



availability of sufficient foreign exchange, the relative size of the debt
service burden, the sovereign debtor's policy toward its principal international
lenders and local political constraints. Sovereign debtors may also be dependent
on expected disbursements from non-U.S. governments, multilateral agencies and
other entities to reduce principal and interest arrearages on their debt. The
failure of a sovereign debtor to implement economic reforms, achieve specified
levels of economic performance or repay principal or interest when due may
result in the cancellation of third-party commitments to lend funds to the
sovereign debtor, which may further impair such debtor's ability or willingness
to service its debts.

EURODOLLAR INSTRUMENTS AND SAMURAI AND YANKEE BONDS The fund may invest in
Eurodollar instruments and Samurai and Yankee bonds. Eurodollar instruments are
bonds of corporate and government issuers that pay interest and principal in
U.S. dollars but are issued in markets outside the United States, primarily in
Europe. Samurai bonds are yen-denominated bonds sold in Japan by non-Japanese
issuers. Yankee bonds are U.S. dollar-denominated bonds typically issued in the
U.S. by non-U.S. governments and their agencies and non-U.S. banks and
corporations. The fund may also invest in Eurodollar Certificates of Deposit
("ECDs"), Eurodollar Time Deposits ("ETDs") and Yankee Certificates of Deposit
("Yankee CDs"). ECDs are U.S. dollar-denominated certificates of deposit issued
by non-U.S. branches of domestic banks; ETDs are U.S. dollar-denominated
deposits in a non-U.S. branch of a U.S. bank or in a non-U.S. bank; and Yankee
CDs are U.S. dollar-denominated certificates of deposit issued by a U.S. branch
of a non-U.S. bank and held in the U.S. These investments involve risks that are
different from investments in securities issued by U.S. issuers, including
potential unfavorable political and economic developments, non-U.S. withholding
or other taxes, seizure of non-U.S. deposits, currency controls, interest
limitations or other governmental restrictions which might affect payment of
principal or interest.

RISKS OF NON-U.S. INVESTMENTS

Investing in securities of non-U.S. issuers involves considerations and risks
not typically associated with investing in the securities of issuers in the U.S.
These risks are heightened with respect to investments in countries with
emerging markets and economies. The risks of investing in securities of non-U.S.
issuers generally, or in issuers with significant exposure to non-U.S. markets
may be related, among other things, to (i) differences in size, liquidity and
volatility of, and the degree and manner of regulation of, the securities
markets of certain non-U.S. markets compared to the securities markets in the
U.S.; (ii) economic, political and social factors; and (iii) foreign exchange
matters, such as restrictions on the repatriation of capital, fluctuations in
exchange rates between the U.S. dollar and the currencies in which the fund's
portfolio securities are quoted or denominated, exchange control regulations and
costs associated with currency exchange. The political and economic structures
in certain countries, particularly emerging markets, are expected to undergo
significant evolution and rapid development, and such countries may lack the
social, political and economic stability characteristic of more developed
countries.

INVESTMENTS IN EMERGING MARKETS. The fund may invest in securities of issuers in
countries with emerging economies or securities markets. Emerging economies or
securities markets will generally include, but not be limited to, countries
included in the MSCI Emerging Markets Index. The fund will generally focus on
emerging markets that do not impose unusual trading requirements which tend to
restrict the flow of investments. In addition, the fund may invest in unquoted
securities, including securities of emerging market issuers.

NON-U.S. SECURITIES MARKETS AND REGULATIONS. There may be less publicly
available information about non-U.S. markets and issuers than is available with
respect to U.S. securities and issuers. Non-U.S. companies generally are not
subject to accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to U.S. companies. The trading
markets for most non-U.S. securities are generally less liquid and subject to
greater price volatility than the markets for


                                       10



comparable securities in the U.S. The markets for securities in certain emerging
markets are in the earliest stages of their development. Even the markets for
relatively widely traded securities in certain non-U.S. markets, including
emerging market countries, may not be able to absorb, without price disruptions,
a significant increase in trading volume or trades of a size customarily
undertaken by institutional investors in the U.S. Additionally, market making
and arbitrage activities are generally less extensive in such markets, which may
contribute to increased volatility and reduced liquidity. The less liquid a
market, the more difficult it may be for the fund to accurately price its
portfolio securities or to dispose of such securities at the times determined by
Pioneer to be appropriate. The risks associated with reduced liquidity may be
particularly acute in situations in which the fund's operations require cash,
such as in order to meet redemptions and to pay its expenses.

ECONOMIC, POLITICAL AND SOCIAL FACTORS. Certain countries, including emerging
markets, may be subject to a greater degree of economic, political and social
instability than is the case in the U.S. and Western European countries. Such
instability may result from, among other things: (i) authoritarian governments
or military involvement in political and economic decision making; (ii) popular
unrest associated with demands for improved economic, political and social
conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring
countries; and (v) ethnic, religious and racial disaffection and conflict. Such
economic, political and social instability could significantly disrupt the
financial markets in such countries and the ability of the issuers in such
countries to repay their obligations. Investing in emerging market countries
also involves the risk of expropriation, nationalization, confiscation of assets
and property or the imposition of restrictions on foreign investments and on
repatriation of capital invested. In the event of such expropriation,
nationalization or other confiscation in any emerging country, the fund could
lose its entire investment in that country.

Certain emerging market countries restrict or control foreign investment in
their securities markets to varying degrees. These restrictions may limit the
fund's investment in those markets and may increase the expenses of the fund. In
addition, the repatriation of both investment income and capital from certain
markets in the region is subject to restrictions such as the need for certain
governmental consents. Even where there is no outright restriction on
repatriation of capital, the mechanics of repatriation may affect certain
aspects of the fund's operation.

Economies in individual countries may differ favorably or unfavorably from the
U.S. economy in such respects as growth of gross domestic product, rates of
inflation, currency valuation, capital reinvestment, resource self-sufficiency
and balance of payments positions. Many countries have experienced substantial,
and in some cases extremely high, rates of inflation for many years. Inflation
and rapid fluctuations in inflation rates have had, and may continue to have,
very negative effects on the economies and securities markets of certain
emerging countries.

Unanticipated political or social developments may affect the values of the
fund's investments in such countries. In the past, the economies, securities and
currency markets of many emerging markets have experienced significant
disruption and declines. There can be no assurance that these economic and
market disruptions might not occur again.

Economies in emerging market countries generally are dependent heavily upon
international trade and, accordingly, have been and may continue to be affected
adversely by trade barriers, exchange controls, managed adjustments in relative
currency values and other protectionist measures imposed or negotiated by the
countries with which they trade. These economies also have been, and may
continue to be, affected adversely by economic conditions in the countries with
which they trade.

CURRENCY RISKS. The value of the securities quoted or denominated in foreign
currencies may be adversely affected by fluctuations in the relative currency
exchange rates and by exchange control


                                       11



regulations. The fund's investment performance may be negatively affected by a
devaluation of a currency in which the fund's investments are quoted or
denominated. Further, the fund's investment performance may be significantly
affected, either positively or negatively, by currency exchange rates because
the U.S. dollar value of securities quoted or denominated in another currency
will increase or decrease in response to changes in the value of such currency
in relation to the U.S. dollar.

CUSTODIAL SERVICES AND RELATED INVESTMENT COSTS. Custodial services and other
costs relating to investment in international securities markets generally are
more expensive than in the U.S. Such markets have settlement and clearance
procedures that differ from those in the U.S. In certain markets there have been
times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the fund to make intended securities purchases due to settlement
problems could cause the fund to miss attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result either in losses to the fund due to a subsequent decline in value of the
portfolio security or could result in possible liability to the fund. In
addition, security settlement and clearance procedures in some emerging
countries may not fully protect the fund against loss or theft of its assets.

WITHHOLDING AND OTHER TAXES. The fund will be subject to taxes, including
withholding taxes, on income (possibly including, in some cases, capital gains)
that are or may be imposed by certain non-U.S. countries with respect to the
fund's investments in such countries. These taxes will reduce the return
achieved by the fund. Treaties between the U.S. and such countries may not be
available to reduce the otherwise applicable tax rates.

INVESTMENTS IN DEPOSITARY RECEIPTS

The fund may hold securities of non-U.S. issuers in the form of American
Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global
Depositary Receipts ("GDRs") and other similar instruments. Generally, ADRs in
registered form are designed for use in U.S. securities markets, and EDRs and
GDRs and other similar global instruments in bearer form are designed for use in
non-U.S. securities markets.

ADRs are denominated in U.S. dollars and represent an interest in the right to
receive securities of non-U.S. issuers deposited in a U.S. bank or correspondent
bank. ADRs do not eliminate all the risk inherent in investing in the securities
of non-U.S. issuers. However, by investing in ADRs rather than directly in
equity securities of non-U.S. issuers, the fund will avoid currency risks during
the settlement period for either purchases or sales. EDRs and GDRs are not
necessarily denominated in the same currency as the underlying securities which
they represent.

For purposes of the fund's investment policies, investments in ADRs, EDRs, GDRs
and similar instruments will be deemed to be investments in the underlying
equity securities of non-U.S. issuers. The fund may acquire depositary receipts
from banks that do not have a contractual relationship with the issuer of the
security underlying the depositary receipt to issue and secure such depositary
receipt. To the extent the fund invests in such unsponsored depositary receipts
there may be an increased possibility that the fund may not become aware of
events affecting the underlying security and thus the value of the related
depositary receipt. In addition, certain benefits (e.g., rights offerings) which
may be associated with the security underlying the depositary receipt may not
inure to the benefit of the holder of such depositary receipt.


                                       12


MORTGAGE-BACKED SECURITIES

The fund may invest in mortgage pass-through certificates and multiple-class
pass-through securities, such as real estate mortgage investment conduits
("REMIC") pass-through certificates, collateralized mortgage obligations
("CMOs") and stripped mortgage-backed securities ("SMBS"), and other types of
mortgage-backed securities that may be available in the future. A
mortgage-backed security is an obligation of the issuer backed by a mortgage or
pool of mortgages or a direct interest in an underlying pool of mortgages. Some
mortgage-backed securities, such as CMOs, make payments of both principal and
interest at a variety of intervals; others make semiannual interest payments at
a predetermined rate and repay principal at maturity (like a typical bond).
Mortgage-backed securities are based on different types of mortgages including
those on commercial real estate or residential properties. Mortgage-backed
securities often have stated maturities of up to thirty years when they are
issued, depending upon the length of the mortgages underlying the securities. In
practice, however, unscheduled or early payments of principal and interest on
the underlying mortgages may make the securities' effective maturity shorter
than this, and the prevailing interest rates may be higher or lower than the
current yield of the fund's portfolio at the time the fund receives the payments
for reinvestment. Mortgage-backed securities may have less potential for capital
appreciation than comparable fixed income securities, due to the likelihood of
increased prepayments of mortgages as interest rates decline. If the fund buys
mortgage-backed securities at a premium, mortgage foreclosures and prepayments
of principal by mortgagors (which may be made at any time without penalty) may
result in some loss of the fund's principal investment to the extent of the
premium paid.

The value of mortgage-backed securities may also change due to shifts in the
market's perception of issuers. In addition, regulatory or tax changes may
adversely affect the mortgage securities markets as a whole. Non-governmental
mortgage-backed securities may offer higher yields than those issued by
government entities, but also may be subject to greater price changes than
governmental issues.

GUARANTEED MORTGAGE PASS-THROUGH SECURITIES. Guaranteed mortgage pass-through
securities represent participation interests in pools of residential mortgage
loans and are issued by U.S. governmental or private lenders and guaranteed by
the U.S. government or one of its agencies or instrumentalities, including but
not limited to GNMA, FNMA and FHLMC. GNMA certificates are guaranteed by the
full faith and credit of the U.S. government for timely payment of principal and
interest on the certificates. FNMA certificates are guaranteed by FNMA, a
federally chartered and privately owned corporation, for full and timely payment
of principal and interest on the certificates. FHLMC certificates are guaranteed
by FHLMC, a corporate instrumentality of the U.S. government, for timely payment
of interest and the ultimate collection of all principal of the related mortgage
loans.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through pools of conventional residential mortgage loans. Such issuers may,
in addition, be the originators and/or servicers of the underlying mortgage
loans as well as the guarantors of the mortgage-related securities. Because
there are no direct or indirect government or agency guarantees of payments in
pools created by such non-governmental issuers, they generally offer a higher
rate of interest than government and government-related pools. Timely payment of
interest and principal of these pools may be supported by insurance or
guarantees, including individual loan, title, pool and hazard insurance and
letters of credit. The insurance and guarantees are issued by governmental
entities, private insurers and the mortgage poolers. There can be no assurance
that the private insurers or guarantors can meet their obligations under the
insurance policies or guarantee arrangements.


                                       13



Mortgage-related securities without insurance or guarantees may be purchased if
Pioneer determines that the securities meet the fund's quality standards.
Mortgage-related securities issued by certain private organizations may not be
readily marketable.

MULTIPLE-CLASS PASS-THROUGH SECURITIES AND COLLATERALIZED MORTGAGE OBLIGATIONS
("CMOS"). CMOs and REMIC pass-through or participation certificates may be
issued by, among others, U.S. government agencies and instrumentalities as well
as private issuers. REMICs are CMO vehicles that qualify for special tax
treatment under the Code and invest in mortgages principally secured by
interests in real property and other investments permitted by the Code. CMOs and
REMIC certificates are issued in multiple classes and the principal of and
interest on the mortgage assets may be allocated among the several classes of
CMOs or REMIC certificates in various ways. Each class of CMO or REMIC
certificate, often referred to as a "tranche," is issued at a specific
adjustable or fixed interest rate and must be fully retired no later than its
final distribution date. Generally, interest is paid or accrues on all classes
of CMOs or REMIC certificates on a monthly basis.

Typically, CMOs are collateralized by GNMA, FNMA or FHLMC certificates but also
may be collateralized by other mortgage assets such as whole loans or private
mortgage pass-through securities. Debt service on CMOs is provided from payments
of principal and interest on collateral of mortgaged assets and any reinvestment
income thereon.


STRIPPED MORTGAGE-BACKED SECURITIES ("SMBS"). SMBS are multiple-class
mortgage-backed securities that are created when a U.S. government agency or a
financial institution separates the interest and principal components of a
mortgage-backed security and sells them as individual securities. The fund
invests in SMBS that are usually structured with two classes that receive
different proportions of interest and principal distributions on a pool of
mortgage assets. A typical SMBS will have one class receiving some of the
interest and most of the principal, while the other class will receive most of
the interest and the remaining principal. The holder of the "principal-only"
security ("PO") receives the principal payments made by the underlying
mortgage-backed security, while the holder of the "interest-only" security
("IO") receives interest payments from the same underlying security. The prices
of SMBS may be particularly affected by changes in interest rates. As interest
rates fall, prepayment rates tend to increase, which tends to reduce prices of
IOs and increase prices of POs. Rising interest rates can have the opposite
effect. Although the market for these securities is increasingly liquid, Pioneer
may determine that certain SMBS issued by the U.S. government, its agencies or
instrumentalities are not readily marketable. The yields and market risk of
interest-only and principal-only SMBS, respectively, may be more volatile than
those of other fixed income securities.


The fund also may invest in planned amortization class ("PAC") and target
amortization class ("TAC") CMO bonds which involve less exposure to prepayment,
extension and interest rate risks than other mortgage-backed securities,
provided that prepayment rates remain within expected prepayment ranges or
"collars." To the extent that the prepayment rates remain within these
prepayment ranges, the residual or support tranches of PAC and TAC CMOs assume
the extra prepayment, extension and interest rate risks associated with the
underlying mortgage assets.

RISK FACTORS ASSOCIATED WITH MORTGAGE-BACKED SECURITIES. Investing in
mortgage-backed securities involves certain risks, including the failure of a
counterparty to meet its commitments, adverse interest rate changes and the
effects of prepayments on mortgage cash flows. In addition, investing in the
lowest tranche of CMOs and REMIC certificates involves risks similar to those
associated with investing in equity securities. However, due to adverse tax
consequences under current tax laws, the fund does not intend to acquire
"residual" interests in REMICs. Further, the yield characteristics of
mortgage-backed securities differ from those of traditional fixed income
securities. The major differences typically include more frequent interest and
principal payments (usually monthly), the adjustability of interest rates of the


                                       14



underlying instrument, and the possibility that prepayments of principal may be
made substantially earlier than their final distribution dates.

Prepayment rates are influenced by changes in current interest rates and a
variety of economic, geographic, social and other factors and cannot be
predicted with certainty. Both adjustable rate mortgage loans and fixed rate
mortgage loans may be subject to a greater rate of principal prepayments in a
declining interest rate environment and to a lesser rate of principal
prepayments in an increasing interest rate environment. Under certain interest
rate and prepayment rate scenarios, the fund may fail to recoup fully its
investment in mortgage-backed securities notwithstanding any direct or indirect
governmental, agency or other guarantee. When the fund reinvests amounts
representing payments and unscheduled prepayments of principal, it may obtain a
rate of interest that is lower than the rate on existing adjustable rate
mortgage pass-through securities. Thus, mortgage-backed securities, and
adjustable rate mortgage pass-through securities in particular, may be less
effective than other types of U.S. government securities as a means of "locking
in" interest rates.

ASSET-BACKED SECURITIES

The fund may invest in asset-backed securities, which are securities that
represent a participation in, or are secured by and payable from, a stream of
payments generated by particular assets, most often a pool or pools of similar
assets (e.g., trade receivables). The credit quality of these securities depends
primarily upon the quality of the underlying assets and the level of credit
support and/or enhancement provided.

The underlying assets (e.g., loans) are subject to prepayments which shorten the
securities' weighted average maturity and may lower their return. If the credit
support or enhancement is exhausted, losses or delays in payment may result if
the required payments of principal and interest are not made. The value of these
securities also may change because of changes in the market's perception of the
creditworthiness of the servicing agent for the pool, the originator of the
pool, or the financial institution or trust providing the credit support or
enhancement. Typically, there is no perfected security interest in the
collateral that relates to the financial assets that support asset-backed
securities.

COLLATERALIZED DEBT OBLIGATIONS

The fund may invest in collateralized debt obligations ("CDOs"), which includes
collateralized bond obligations ("CBOs"), collateralized loan obligations
("CLOs") and other similarly structured securities. A CBO is a trust backed by a
pool of fixed income securities. A CLO is a trust typically collateralized by a
pool of loans, which may include, among others, domestic and foreign senior
secured loans, senior unsecured loans, and subordinate corporate loans,
including loans that may be rated below investment grade or equivalent unrated
loans. CDOs may charge management fees and administrative expenses.

The CBO trust is typically split into two or more portions, called tranches,
varying in credit quality and yield. The riskiest portion is the "equity"
tranche which bears the bulk of defaults from the bonds or loans in the trust
and serves to protect the other, more senior tranches from default in all but
the most severe circumstances. Since it is partially protected from defaults, a
senior tranche from a CBO trust or CLO trust typically have higher ratings and
lower yields than their underlying securities, and can be rated investment
grade. Despite the protection from the equity tranche, CBO or CLO tranches can
experience substantial losses due to actual defaults, increased sensitivity to
defaults due to collateral default and disappearance of protecting tranches,
market anticipation of defaults, as well as aversion to CBO or CLO securities as
a class.

The risks of an investment in a CDO depend largely on the type of the collateral
securities and the class of the CDO in which the fund invests. Normally, CBOs,
CLOs and other CDOs are privately offered and sold, and thus, are not registered
under the securities laws. As a result, investments in CDOs may be


                                       15



characterized by the fund as illiquid securities, however an active dealer
market may exist for CDOs allowing a CDO to qualify for Rule 144A transactions.
In addition to the normal risks associated with fixed income securities (e.g.,
interest rate risk and default risk), CDOs carry additional risks including, but
are not limited to: (i) the possibility that distributions from collateral
securities will not be adequate to make interest or other payments; (ii) the
quality of the collateral may decline in value or default; (iii) the fund may
invest in CDOs that are subordinate to other classes; and (iv) the complex
structure of the security may not be fully understood at the time of investment
and may produce disputes with the issuer or unexpected investment results.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

The fund may purchase securities, including U.S. government securities, on a
when-issued basis or may purchase or sell securities for delayed delivery. In
such transactions, delivery of the securities occurs beyond the normal
settlement period, but no payment or delivery is made by the fund prior to the
actual delivery or payment by the other party to the transaction. The fund will
not earn income on these securities until delivered. The purchase of securities
on a when-issued or delayed delivery basis involves the risk that the value of
the securities purchased will decline prior to the settlement date. The sale of
securities for delayed delivery involves the risk that the prices available in
the market on the delivery date may be greater than those obtained in the sale
transaction. The fund's obligations with respect to when-issued and delayed
delivery transactions will be fully collateralized by segregating liquid assets
with a value equal to the fund's obligations. See "Asset Segregation."

INVESTMENTS IN EQUITY SECURITIES

Equity securities, such as common stock, generally represent an ownership
interest in a company. While equity securities have historically generated
higher average returns than fixed income securities, equity securities have also
experienced significantly more volatility in those returns. An adverse event,
such as an unfavorable earnings report, may depress the value of a particular
equity security held by the fund. Also, the price of equity securities,
particularly common stocks, are sensitive to general movements in the stock
market. A drop in the stock market may depress the price of equity securities
held by the fund.

WARRANTS AND STOCK PURCHASE RIGHTS

The fund may invest in warrants, which are securities permitting, but not
obligating, their holder to subscribe for other securities. Warrants do not
carry with them the right to dividends or voting rights with respect to the
securities that they entitle their holders to purchase, and they do not
represent any rights in the assets of the issuer.

The fund may also invest in stock purchase rights. Stock purchase rights are
instruments, frequently distributed to an issuer's shareholders as a dividend,
that entitle the holder to purchase a specific number of shares of common stock
on a specific date or during a specific period of time. The exercise price on
the rights is normally at a discount from market value of the common stock at
the time of distribution. The rights do not carry with them the right to
dividends or to vote and may or may not be transferable. Stock purchase rights
are frequently used outside of the United States as a means of raising
additional capital from an issuer's current shareholders.

As a result, an investment in warrants or stock purchase rights may be
considered more speculative than certain other types of investments. In
addition, the value of a warrant or a stock purchase right does not necessarily
change with the value of the underlying securities, and warrants and stock
purchase rights expire worthless if they are not exercised on or prior to their
expiration date.


                                       16



OTHER INVESTMENT COMPANIES

The fund may invest in the securities of other investment companies to the
extent that such investments are consistent with the fund's investment
objectives and policies and permissible under the Investment Company Act of
1940, as amended (the "1940 Act"). Under one provision of the 1940 Act, a fund
may not acquire the securities of another investment company if, as a result,
(i) more than 10% of the fund's total assets would be invested in securities of
other investment companies, (ii) such purchase would result in more than 3% of
the total outstanding voting securities of any one investment company being held
by the fund, or (iii) more than 5% of the fund's total assets would be invested
in any one investment company. However, there are several provisions of the 1940
Act and rules thereunder that allow more expansive investment in investment
companies.

The fund, as a holder of the securities of other investment companies, will bear
its pro rata portion of the other investment companies' expenses, including
advisory fees. These expenses are in addition to the direct expenses of the
fund's own operations.

EXCHANGE TRADED FUNDS

Subject to the limitations on investment in other investment companies, the fund
may invest in exchange traded funds (ETFs). ETFs, such as SPDRs, PowerShares
QQQ(TM) (QQQQs), iShares and various country index funds, are funds whose shares
are traded on a national exchange or the National Association of Securities
Dealers' Automatic Quotation System (NASDAQ). ETFs may be based on underlying
equity or fixed income securities. SPDRs, for example, seek to provide
investment results that generally correspond to the performance of the component
common stocks of the S&P 500. ETFs do not sell individual shares directly to
investors and only issue their shares in large blocks known as "creation units."
The investor purchasing a creation unit then sells the individual shares on a
secondary market. Therefore, the liquidity of ETFs depends on the adequacy of
the secondary market. There can be no assurance that an ETF's investment
objective will be achieved. ETFs based on an index may not replicate and
maintain exactly the composition and relative weightings of securities in the
index. ETFs are subject to the risks of investing in the underlying securities.
The fund, as a holder of the securities of the ETF, will bear its pro rata
portion of the ETF's expenses, including advisory fees. These expenses are in
addition to the direct expenses of the fund's own operations.

REPURCHASE AGREEMENTS

The fund may enter into repurchase agreements with broker-dealers, member banks
of the Federal Reserve System and other financial institutions. Repurchase
agreements are arrangements under which the fund purchases securities and the
seller agrees to repurchase the securities within a specific time and at a
specific price. The repurchase price is generally higher than the fund's
purchase price, with the difference being income to the fund. Under the
direction of the Board of Trustees, Pioneer reviews and monitors the
creditworthiness of any institution which enters into a repurchase agreement
with the fund. The counterparty's obligations under the repurchase agreement are
collateralized with U.S. Treasury and/or agency obligations with a market value
of not less than 100% of the obligations, valued daily. Collateral is held by
the fund's custodian in a segregated, safekeeping account for the benefit of the
fund. Repurchase agreements afford the fund an opportunity to earn income on
temporarily available cash at low risk. In the event of commencement of
bankruptcy or insolvency proceedings with respect to the seller of the security
before repurchase of the security under a repurchase agreement, the fund may
encounter delay and incur costs before being able to sell the security. Such a
delay may involve loss of interest or a decline in price of the security. If the
court characterizes the transaction as a loan and the fund has not perfected a
security interest in the security, the fund may be required to return the
security to


                                       17



the seller's estate and be treated as an unsecured creditor of the seller. As an
unsecured creditor, the fund would be at risk of losing some or all of the
principal and interest involved in the transaction.

SHORT SALES AGAINST THE BOX

The fund may sell securities "short against the box." A short sale involves the
fund borrowing securities from a broker and selling the borrowed securities. The
fund has an obligation to return securities identical to the borrowed securities
to the broker. In a short sale against the box, the fund at all times owns an
equal amount of the security sold short or securities convertible into or
exchangeable for, with or without payment of additional consideration, an equal
amount of the security sold short. The fund intends to use short sales against
the box to hedge. For example when the fund believes that the price of a current
portfolio security may decline, the fund may use a short sale against the box to
lock in a sale price for a security rather than selling the security
immediately. In such a case, any future losses in the fund's long position
should be offset by a gain in the short position and, conversely, any gain in
the long position should be reduced by a loss in the short position.

If the fund effects a short sale against the box at a time when it has an
unrealized gain on the security, it may be required to recognize that gain as if
it had actually sold the security (a "constructive sale") on the date it effects
the short sale. However, such constructive sale treatment may not apply if the
fund closes out the short sale with securities other than the appreciated
securities held at the time of the short sale provided that certain other
conditions are satisfied. Uncertainty regarding the tax consequences of
effecting short sales may limit the extent to which the fund may make short
sales against the box.

ASSET SEGREGATION

The 1940 Act requires that the fund segregate assets in connection with certain
types of transactions that may have the effect of leveraging the fund's
portfolio. If the fund enters into a transaction requiring segregation, such as
a forward commitment, the custodian or Pioneer will segregate liquid assets in
an amount required to comply with the 1940 Act. Such segregated assets will be
valued at market daily. If the aggregate value of such segregated assets
declines below the aggregate value required to satisfy the 1940 Act, additional
liquid assets will be segregated.

PORTFOLIO TURNOVER

It is the policy of the fund not to engage in trading for short-term profits
although portfolio turnover rate is not considered a limiting factor in the
execution of investment decisions for the fund. A high rate of portfolio
turnover (100% or more) involves correspondingly greater transaction costs which
must be borne by the fund and its shareholders. See "Annual Fee, Expense and
Other Information" for the fund's annual portfolio turnover rate.

STRUCTURED SECURITIES

The fund may invest in structured securities. The value of the principal and/or
interest on such securities may be determined by reference to changes in the
value of specific currencies, interest rates, commodities, indices or other
financial indicators (the "Reference") or the relative change in two or more
References. The interest rate or the principal amount payable upon maturity or
redemption may be increased or decreased depending upon changes in the
Reference. The terms of the structured securities may provide in certain
circumstances that no principal is due at maturity and, therefore may result in
a loss of the fund's investment. Changes in the interest rate or principal
payable at maturity may be a multiple of the changes in the value of the
Reference. Consequently, structured securities may entail a greater degree of
market risk than other types of fixed income securities.


                                       18



HYBRID INSTRUMENTS

The fund may invest in "hybrid" instruments that combine the characteristics of
securities, futures, and options. For example, the principal amount or interest
of a hybrid could be tied (positively or negatively) to the price of some
securities index or another interest rate (each a "benchmark"). The interest
rate or (unlike many debt obligations) the principal amount payable at maturity
of a hybrid security may be increased or decreased, depending on changes in the
value of the benchmark. Hybrids can be used as an efficient means of pursuing a
variety of investment goals, including duration management and increased total
return. Hybrids may not bear interest or pay dividends. The value of a hybrid or
its interest rate may be a multiple of a benchmark and, as a result, may be
leveraged and move (up or down) more steeply and rapidly than the benchmark.
These benchmarks may be sensitive to economic and political events that cannot
be readily foreseen by the purchaser of a hybrid. Under certain conditions, the
redemption value of a hybrid could be zero. Thus, an investment in a hybrid may
entail significant market risks that are not associated with a similar
investment in a traditional, U.S. dollar-denominated bond that has a fixed
principal amount and pays a fixed rate or floating rate of interest. The
purchase of hybrids also exposes the fund to the credit risk of the issuer of
the hybrids. These risks may cause significant fluctuations in the net asset
value of the fund.

FOREIGN CURRENCY TRANSACTIONS

The fund may engage in foreign currency transactions. These transactions may be
conducted at the prevailing spot rate for purchasing or selling currency in the
foreign exchange market. The fund also has authority to enter into forward
foreign currency exchange contracts involving currencies of the different
countries in which the fund invests as a hedge against possible variations in
the foreign exchange rates between these currencies and the U.S. dollar. This is
accomplished through contractual agreements to purchase or sell a specified
currency at a specified future date and price set at the time of the contract.

Transaction hedging is the purchase or sale of forward foreign currency
contracts with respect to specific receivables or payables of the fund, accrued
in connection with the purchase and sale of its portfolio securities quoted in
foreign currencies. Portfolio hedging is the use of forward foreign currency
contracts to offset portfolio security positions denominated or quoted in such
foreign currencies. There is no guarantee that the fund will be engaged in
hedging activities when adverse exchange rate movements occur. The fund will not
attempt to hedge all of its foreign portfolio positions and will enter into such
transactions only to the extent, if any, deemed appropriate by Pioneer.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also limit the opportunity
for gain if the value of the hedged currency should rise. Moreover, it may not
be possible for the fund to hedge against a devaluation that is so generally
anticipated that the fund is not able to contract to sell the currency at a
price above the devaluation level it anticipates.

The fund may also engage in cross-hedging by using forward contracts in one
currency to hedge against fluctuations in the value of securities denominated in
a different currency, if Pioneer determines that there is a pattern of
correlation between the two currencies. Cross-hedging may also include entering
into a forward transaction involving two foreign currencies, using one foreign
currency as a proxy for the U.S. dollar to hedge against variations in the other
foreign currency, if Pioneer determines that there is a pattern of correlation
between the proxy currency and the U.S. dollar.

The cost to the fund of engaging in foreign currency transactions varies with
such factors as the currency involved, the size of the contract, the length of
the contract period, differences in interest rates between


                                       19



the two currencies and the market conditions then prevailing. Since transactions
in foreign currency and forward contracts are usually conducted on a principal
basis, no fees or commissions are involved. The fund may close out a forward
position in a currency by selling the forward contract or by entering into an
offsetting forward contract.

The precise matching of the forward contract amounts and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures. Using forward contracts to
protect the value of the fund's portfolio securities against a decline in the
value of a currency does not eliminate fluctuations in the underlying prices of
the securities. It simply establishes a rate of exchange which the fund can
achieve at some future point in time. The precise projection of short-term
currency market movements is not possible, and short-term hedging provides a
means of fixing the U.S. dollar value of only a portion of the fund's foreign
assets.

While the fund will enter into forward contracts to reduce currency exchange
rate risks, transactions in such contracts involve certain other risks. While
the fund may benefit from such transactions, unanticipated changes in currency
prices may result in a poorer overall performance for the fund than if it had
not engaged in any such transactions. Moreover, there may be imperfect
correlation between the fund's portfolio holdings of securities quoted or
denominated in a particular currency and forward contracts entered into by the
fund. Such imperfect correlation may cause the fund to sustain losses which will
prevent the fund from achieving a complete hedge or expose the fund to risk of
foreign exchange loss.

Over-the-counter markets for trading foreign forward currency contracts offer
less protection against defaults than is available when trading in currency
instruments on an exchange. Since a forward foreign currency exchange contract
is not guaranteed by an exchange or clearinghouse, a default on the contract
would deprive the fund of unrealized profits or force the fund to cover its
commitments for purchase or resale, if any, at the current market price.

If the fund enters into a forward contract to purchase foreign currency, the
custodian or Pioneer will segregate liquid assets. See "Asset Segregation."

OPTIONS ON FOREIGN CURRENCIES

The fund may purchase and write options on foreign currencies for hedging
purposes in a manner similar to that of transactions in forward contracts. For
example, a decline in the dollar value of a foreign currency in which portfolio
securities are quoted or denominated will reduce the dollar value of such
securities, even if their value in the foreign currency remains constant. In an
attempt to protect against such decreases in the value of portfolio securities,
the fund may purchase put options on the foreign currency. If the value of the
currency declines, the fund will have the right to sell such currency for a
fixed amount of dollars which exceeds the market value of such currency. This
would result in a gain that may offset, in whole or in part, the negative effect
of currency depreciation on the value of the fund's securities quoted or
denominated in that currency.

Conversely, if a rise in the dollar value of a currency is projected for those
securities to be acquired, thereby increasing the cost of such securities, the
fund may purchase call options on such currency. If the value of such currency
increases, the purchase of such call options would enable the fund to purchase
currency for a fixed amount of dollars which is less than the market value of
such currency. Such a purchase would result in a gain that may offset, at least
partially, the effect of any currency-related increase in the price of
securities the fund intends to acquire. As in the case of other types of options


                                       20



transactions, however, the benefit the fund derives from purchasing foreign
currency options will be reduced by the amount of the premium and related
transaction costs. In addition, if currency exchange rates do not move in the
direction or to the extent anticipated, the fund could sustain losses on
transactions in foreign currency options which would deprive it of a portion or
all of the benefits of advantageous changes in such rates.

The fund may also write options on foreign currencies for hedging purposes. For
example, if the fund anticipated a decline in the dollar value of securities
quoted or denominated in a foreign currency because of declining exchange rates,
it could, instead of purchasing a put option, write a covered call option on the
relevant currency. If the expected decline occurs, the option will most likely
not be exercised, and the decrease in value of portfolio securities will be
partially offset by the amount of the premium received by the fund.

Similarly, the fund could write a put option on the relevant currency, instead
of purchasing a call option, to hedge against an anticipated increase in the
dollar cost of securities to be acquired. If exchange rates move in the manner
projected, the put option will expire unexercised and allow the fund to offset
such increased cost up to the amount of the premium. However, as in the case of
other types of options transactions, the writing of a foreign currency option
will constitute only a partial hedge up to the amount of the premium, only if
rates move in the expected direction. If unanticipated exchange rate
fluctuations occur, the option may be exercised and the fund would be required
to purchase or sell the underlying currency at a loss which may not be fully
offset by the amount of the premium. As a result of writing options on foreign
currencies, the fund also may be required to forgo all or a portion of the
benefits which might otherwise have been obtained from favorable movements in
currency exchange rates.

A call option written on foreign currency by the fund is "covered" if the fund
owns the underlying foreign currency subject to the call, or if it has an
absolute and immediate right to acquire that foreign currency without additional
cash consideration. A call option is also covered if the fund holds a call on
the same foreign currency for the same principal amount as the call written
where the exercise price of the call held is (a) equal to or less than the
exercise price of the call written or (b) greater than the exercise price of the
call written if the amount of the difference is maintained by the fund in cash
or liquid securities. See "Asset Segregation."

The fund may close out its position in a currency option by either selling the
option it has purchased or entering into an offsetting option. An
exchange-traded options position may be closed out only on an options exchange
which provides a secondary market for an option of the same series. Although the
fund will generally purchase or write only those options for which there appears
to be an active secondary market, there is no assurance that a liquid secondary
market on an exchange will exist for any particular option, or at any particular
time. For some options no secondary market on an exchange may exist. In such
event, it might not be possible to effect closing transactions in particular
options, with the result that the fund would have to exercise its options in
order to realize any profit and would incur transaction costs upon the sale of
underlying currencies pursuant to the exercise of put options. If the fund as a
covered call option writer is unable to effect a closing purchase transaction in
a secondary market, it will not be able to sell the underlying currency (or
security quoted or denominated in that currency) until the option expires or it
delivers the underlying currency upon exercise.

The fund may also use options on currencies to cross-hedge, which involves
writing or purchasing options on one currency to hedge against changes in
exchange rates of a different currency with a pattern of correlation. Cross
hedging may also include using a foreign currency as a proxy for the U.S.
dollar, if Pioneer determines that there is a pattern of correlation between
that currency and the U.S. dollar.


                                       21




The fund may purchase and write over-the-counter options. Trading in
over-the-counter options is subject to the risk that the other party will be
unable or unwilling to close out options purchased or written by the fund.


OPTIONS ON SECURITIES AND SECURITIES INDICES

For hedging purposes or to seek to increase total return, the fund may purchase
put and call options on any security in which it may invest or options on any
securities index based on securities in which it may invest. The fund would also
be able to enter into closing sale transactions in order to realize gains or
minimize losses on options it has purchased.

WRITING CALL AND PUT OPTIONS ON SECURITIES. A call option written by the fund
obligates the fund to sell specified securities to the holder of the option at a
specified price if the option is exercised at any time before the expiration
date. All call options written by the fund are covered, which means that the
fund will own the securities subject to the options as long as the options are
outstanding, or the fund will use the other methods described below. The fund's
purpose in writing covered call options is to realize greater income than would
be realized on portfolio securities transactions alone. However, the fund may
forgo the opportunity to profit from an increase in the market price of the
underlying security.

A put option written by the fund would obligate the fund to purchase specified
securities from the option holder at a specified price if the option is
exercised at any time before the expiration date. All put options written by the
fund would be covered, which means that the fund would have segregated assets
with a value at least equal to the exercise price of the put option. The purpose
of writing such options is to generate additional income for the fund. However,
in return for the option premium, the fund accepts the risk that it may be
required to purchase the underlying security at a price in excess of its market
value at the time of purchase.

Call and put options written by the fund will also be considered to be covered
to the extent that the fund's liabilities under such options are wholly or
partially offset by its rights under call and put options purchased by the fund.
In addition, a written call or put option may be covered by entering into an
offsetting forward contract and/or by purchasing an offsetting option or any
other option which, by virtue of its exercise price or otherwise, reduces the
fund's net exposure on its written option position.

WRITING CALL AND PUT OPTIONS ON SECURITIES INDICES. The fund may also write
(sell) covered call and put options on any securities index composed of
securities in which it may invest. Options on securities indices are similar to
options on securities, except that the exercise of securities index options
requires cash payments and does not involve the actual purchase or sale of
securities. In addition, securities index options are designed to reflect price
fluctuations in a group of securities or segments of the securities market
rather than price fluctuations in a single security.

The fund may cover call options on a securities index by owning securities whose
price changes are expected to be similar to those of the underlying index, or by
having an absolute and immediate right to acquire such securities without
additional cash consideration (or for additional consideration if cash in such
amount is segregated) upon conversion or exchange of other securities in its
portfolio. The fund may cover call and put options on a securities index by
segregating assets with a value equal to the exercise price.

PURCHASING CALL AND PUT OPTIONS. The fund would normally purchase call options
in anticipation of an increase in the market value of securities of the type in
which it may invest. The purchase of a call option would entitle the fund, in
return for the premium paid, to purchase specified securities at a specified
price during the option period. The fund would ordinarily realize a gain if,
during the option period, the value


                                       22



of such securities exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise the fund would realize either no gain or a loss on
the purchase of the call option.

The fund would normally purchase put options in anticipation of a decline in the
market value of securities in its portfolio ("protective puts") or in securities
in which it may invest. The purchase of a put option would entitle the fund, in
exchange for the premium paid, to sell specified securities at a specified price
during the option period. The purchase of protective puts is designed to offset
or hedge against a decline in the market value of the fund's securities. Put
options may also be purchased by the fund for the purpose of affirmatively
benefiting from a decline in the price of securities which it does not own. The
fund would ordinarily realize a gain if, during the option period, the value of
the underlying securities decreased below the exercise price sufficiently to
more than cover the premium and transaction costs; otherwise the fund would
realize either no gain or a loss on the purchase of the put option. Gains and
losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of the underlying portfolio securities.

The fund may terminate its obligations under an exchange-traded call or put
option by purchasing an option identical to the one it has written. Obligations
under over-the-counter options may be terminated only by entering into an
offsetting transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

RISKS OF TRADING OPTIONS. There is no assurance that a liquid secondary market
on an options exchange will exist for any particular exchange-traded option, or
at any particular time. If the fund is unable to effect a closing purchase
transaction with respect to covered options it has written, the fund will not be
able to sell the underlying securities or dispose of its segregated assets until
the options expire or are exercised. Similarly, if the fund is unable to effect
a closing sale transaction with respect to options it has purchased, it will
have to exercise the options in order to realize any profit and will incur
transaction costs upon the purchase or sale of underlying securities.

Reasons for the absence of a liquid secondary market on an exchange include the
following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation (the "OCC")
may not at all times be adequate to handle current trading volume; or (vi) one
or more exchanges could, for economic or other reasons, decide or be compelled
at some future date to discontinue the trading of options (or a particular class
or series of options), in which event the secondary market on that exchange (or
in that class or series of options) would cease to exist, although outstanding
options on that exchange, if any, that had been issued by the OCC as a result of
trades on that exchange would continue to be exercisable in accordance with
their terms.

The fund may purchase and sell both options that are traded on U.S. and non-U.S.
exchanges and options traded over-the-counter with broker-dealers who make
markets in these options. The ability to terminate over-the-counter options is
more limited than with exchange-traded options and may involve the risk that
broker-dealers participating in such transactions will not fulfill their
obligations. Until such time as the staff of the Securities and Exchange
Commission (the "SEC") changes its position, the fund will treat purchased
over-the-counter options and all assets used to cover written over-the-counter
options as illiquid securities, except that with respect to options written with
primary dealers in U.S. government securities pursuant to an agreement requiring
a closing purchase transaction at a formula price, the amount of illiquid
securities may be calculated with reference to the formula.


                                       23



Transactions by the fund in options on securities and indices will be subject to
limitations established by each of the exchanges, boards of trade or other
trading facilities governing the maximum number of options in each class which
may be written or purchased by a single investor or group of investors acting in
concert. Thus, the number of options which the fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
Pioneer. An exchange, board of trade or other trading facility may order the
liquidations of positions found to be in excess of these limits, and it may
impose certain other sanctions.

The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The successful use of protective
puts for hedging purposes depends in part on Pioneer's ability to predict future
price fluctuations and the degree of correlation between the options and
securities markets.

The hours of trading for options may not conform to the hours during which the
underlying securities are traded. To the extent that the options markets close
before the markets for the underlying securities, significant price movements
can take place in the underlying markets that cannot be reflected in the options
markets.

In addition to the risks of imperfect correlation between the fund's portfolio
and the index underlying the option, the purchase of securities index options
involves the risk that the premium and transaction costs paid by the fund in
purchasing an option will be lost. This could occur as a result of unanticipated
movements in the price of the securities comprising the securities index on
which the option is based.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

To hedge against changes in securities prices or currency exchange rates or to
seek to increase total return, the fund may purchase and sell various kinds of
futures contracts, and purchase and write (sell) call and put options on any of
such futures contracts. The fund may also enter into closing purchase and sale
transactions with respect to any of such contracts and options. The futures
contracts may be based on various securities (such as U.S. government
securities), securities indices, foreign currencies and other financial
instruments and indices. The fund will engage in futures and related options
transactions for bona fide hedging and non-hedging purposes as described below.
All futures contracts entered into by the fund are traded on U.S. exchanges or
boards of trade that are licensed and regulated by the Commodity Futures Trading
Commission (the "CFTC") or on non-U.S. exchanges.

FUTURES CONTRACTS. A futures contract may generally be described as an agreement
between two parties to buy and sell particular financial instruments for an
agreed price during a designated month (or to deliver the final cash settlement
price, in the case of a contract relating to an index or otherwise not calling
for physical delivery at the end of trading in the contract).

When interest rates are rising or securities prices are falling, the fund can
seek to offset a decline in the value of its current portfolio securities
through the sale of futures contracts. When interest rates are falling or
securities prices are rising, the fund, through the purchase of futures
contracts, can attempt to secure better rates or prices than might later be
available in the market when it effects anticipated purchases. Similarly, the
fund can sell futures contracts on a specified currency to protect against a
decline in the value of such currency and a decline in the value of its
portfolio securities which are denominated in such currency. The fund can
purchase futures contracts on a foreign currency to establish the price in U.S.
dollars of a security denominated in such currency that the fund has acquired or
expects to acquire.

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting transactions which may result in a profit
or a loss. While futures contracts on securities or


                                       24



currency will usually be liquidated in this manner, the fund may instead make,
or take, delivery of the underlying securities or currency whenever it appears
economically advantageous to do so. A clearing corporation associated with the
exchange on which futures on securities or currency are traded guarantees that,
if still open, the sale or purchase will be performed on the settlement date.

HEDGING STRATEGIES. Hedging, by use of futures contracts, seeks to establish
with more certainty the effective price, rate of return and currency exchange
rate on portfolio securities and securities that the fund owns or proposes to
acquire. The fund may, for example, take a "short" position in the futures
market by selling futures contracts in order to hedge against an anticipated
rise in interest rates or a decline in market prices or foreign currency rates
that would adversely affect the value of the fund's portfolio securities. Such
futures contracts may include contracts for the future delivery of securities
held by the fund or securities with characteristics similar to those of the
fund's portfolio securities. Similarly, the fund may sell futures contracts in a
foreign currency in which its portfolio securities are denominated or in one
currency to hedge against fluctuations in the value of securities denominated in
a different currency if there is an established historical pattern of
correlation between the two currencies. If, in the opinion of Pioneer, there is
a sufficient degree of correlation between price trends for the fund's portfolio
securities and futures contracts based on other financial instruments,
securities indices or other indices, the fund may also enter into such futures
contracts as part of its hedging strategies. Although under some circumstances
prices of securities in the fund's portfolio may be more or less volatile than
prices of such futures contracts, Pioneer will attempt to estimate the extent of
this volatility difference based on historical patterns and compensate for any
such differential by having the fund enter into a greater or lesser number of
futures contracts or by attempting to achieve only a partial hedge against price
changes affecting the fund's portfolio securities. When hedging of this
character is successful, any depreciation in the value of portfolio securities
will be substantially offset by appreciation in the value of the futures
position. On the other hand, any unanticipated appreciation in the value of the
fund's portfolio securities would be substantially offset by a decline in the
value of the futures position.

On other occasions, the fund may take a "long" position by purchasing futures
contracts. This may be done, for example, when the fund anticipates the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices or currency exchange rates then available in the applicable
market to be less favorable than prices or rates that are currently available.

OPTIONS ON FUTURES CONTRACTS. The acquisition of put and call options on futures
contracts will give the fund the right (but not the obligation) for a specified
price to sell or to purchase, respectively, the underlying futures contract at
any time during the option period. As the purchaser of an option on a futures
contract, the fund obtains the benefit of the futures position if prices move in
a favorable direction but limits its risk of loss in the event of an unfavorable
price movement to the loss of the premium and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the fund's assets. By writing a call
option, the fund becomes obligated, in exchange for the premium, to sell a
futures contract (if the option is exercised), which may have a value higher
than the exercise price. Conversely, the writing of a put option on a futures
contract generates a premium which may partially offset an increase in the price
of securities that the fund intends to purchase. However, the fund becomes
obligated to purchase a futures contract (if the option is exercised) which may
have a value lower than the exercise price. Thus, the loss incurred by the fund
in writing options on futures is potentially unlimited and may exceed the amount
of the premium received. The fund will incur transaction costs in connection
with the writing of options on futures.

The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same series. There
is no guarantee that such closing transactions can be


                                       25



effected. The fund's ability to establish and close out positions on such
options will be subject to the development and maintenance of a liquid market.

OTHER CONSIDERATIONS. The fund will engage in futures and related options
transactions only in accordance with CFTC regulations which permit principals of
an investment company registered under the 1940 Act to engage in such
transactions without registering as commodity pool operators.

The fund will engage in transactions in futures contracts and related options
only to the extent such transactions are consistent with the requirements of the
Code for maintaining its qualification as a regulated investment company for
U.S. federal income tax purposes.

Futures contracts and related options involve brokerage costs, require margin
deposits and, in the case of contracts and options obligating the fund to
purchase securities or currencies, require the fund to segregate assets to cover
such contracts and options.

While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks. Thus,
while the fund may benefit from the use of futures and options on futures,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for the fund than if it had not
entered into any futures contracts or options transactions. In the event of an
imperfect correlation between a futures position and a portfolio position which
is intended to be protected, the desired protection may not be obtained and the
fund may be exposed to risk of loss. It is not possible to hedge fully or
perfectly against the effect of currency fluctuations on the value of non-U.S.
securities because currency movements impact the value of different securities
in differing degrees.

INTEREST RATE SWAPS, COLLARS, CAPS AND FLOORS

In order to hedge the value of the fund's portfolio against interest rate
fluctuations or to enhance the fund's income, the fund may, but is not required
to, enter into various interest rate transactions such as interest rate swaps
and the purchase or sale of interest rate caps and floors. To the extent that
the fund enters into these transactions, the fund expects to do so primarily to
preserve a return or spread on a particular investment or portion of its
portfolio or to protect against any increase in the price of securities the fund
anticipates purchasing at a later date. The fund intends to use these
transactions primarily as a hedge and not as a speculative investment. However,
the fund also may invest in interest rate swaps to enhance income or to increase
the fund's yield, for example, during periods of steep interest rate yield
curves (i.e., wide differences between short-term and long-term interest rates).
The fund is not required to hedge its portfolio and may choose not to do so. The
fund cannot guarantee that any hedging strategies it uses will work.

In an interest rate swap, the fund exchanges with another party their respective
commitments to pay or receive interest (e.g., an exchange of fixed rate payments
for floating rate payments). For example, if the fund holds a debt instrument
with an interest rate that is reset only once each year, it may swap the right
to receive interest at this fixed rate for the right to receive interest at a
rate that is reset every week. This would enable the fund to offset a decline in
the value of the debt instrument due to rising interest rates but would also
limit its ability to benefit from falling interest rates. Conversely, if the
fund holds a debt instrument with an interest rate that is reset every week and
it would like to lock in what it believes to be a high interest rate for one
year, it may swap the right to receive interest at this variable weekly rate for
the right to receive interest at a rate that is fixed for one year. Such a swap
would protect the fund from a reduction in yield due to falling interest rates
and may permit the fund to enhance its income through the positive differential
between one week and one year interest rates, but would preclude it from taking
full advantage of rising interest rates.


                                       26


The fund usually will enter into interest rate swaps on a net basis (i.e., the
two payment streams are netted out with the fund receiving or paying, as the
case may be, only the net amount of the two payments). The net amount of the
excess, if any, of the fund's obligations over its entitlements with respect to
each interest rate swap will be accrued on a daily basis, and an amount of cash
or liquid instruments having an aggregate net asset value at least equal to the
accrued excess will be maintained in a segregated account by the fund's
custodian. If the interest rate swap transaction is entered into on other than a
net basis, the full amount of the fund's obligations will be accrued on a daily
basis, and the full amount of the fund's obligations will be maintained in a
segregated account by the fund's custodian.

The fund also may engage in interest rate transactions in the form of purchasing
or selling interest rate caps or floors. The fund will not sell interest rate
caps or floors that it does not own. The purchase of an interest rate cap
entitles the purchaser, to the extent that a specified index exceeds a
predetermined interest rate, to receive payments of interest equal to the
difference of the index and the predetermined rate on a notional principal
amount (i.e., the reference amount with respect to which interest obligations
are determined although no actual exchange of principal occurs) from the party
selling such interest rate cap. The purchase of an interest rate floor entitles
the purchaser, to the extent that a specified index falls below a predetermined
interest rate, to receive payments of interest at the difference of the index
and the predetermined rate on a notional principal amount from the party selling
such interest rate floor. The fund will not enter into caps or floors if, on a
net basis, the aggregate notional principal amount with respect to such
agreements exceeds the net assets of the fund.

Typically, the parties with which the fund will enter into interest rate
transactions will be broker-dealers and other financial institutions. The fund
will not enter into any interest rate swap, cap or floor transaction unless the
unsecured senior debt or the claims-paying ability of the other party thereto is
rated investment grade quality by at least one nationally recognized statistical
rating organization at the time of entering into such transaction or whose
creditworthiness is believed by the fund's adviser to be equivalent to such
rating. If there is a default by the other party to such a transaction, the fund
will have contractual remedies pursuant to the agreements related to the
transaction. The swap market has grown substantially in recent years with a
large number of banks and investment banking firms acting both as principals and
as agents utilizing standardized swap documentation. As a result, the swap
market has become relatively liquid in comparison with other similar instruments
traded in the interbank market. Caps and floors, however, are less liquid than
swaps. Certain federal income tax requirements may limit the fund's ability to
engage in interest rate swaps.

CREDIT DEFAULT SWAP AGREEMENTS

The fund may enter into credit default swap agreements. The "buyer" in a credit
default contract is obligated to pay the "seller" a periodic stream of payments
over the term of the contract provided that no event of default on an underlying
reference obligation has occurred. If an event of default occurs, the seller
must pay the buyer the "par value" (full notional value) of the reference
obligation in exchange for the reference obligation. The fund may be either the
buyer or seller in the transaction. If the fund is a buyer and no event of
default occurs, the fund loses its investment and recovers nothing. However, if
an event of default occurs, the buyer receives full notional value for a
reference obligation that may have little or no value. As a seller, the fund
receives a fixed rate of income throughout the term of the contract, which
typically is between six months and three years, provided that there is no
default event. If an event of default occurs, the seller must pay the buyer the
full notional value of the reference obligation. Credit default swaps involve
greater risks than if the fund had invested in the reference obligation
directly. In addition to general market risks, credit default swaps are subject
to illiquidity risk, counterparty risk and credit risks. The fund will enter
into swap agreements only with counterparties who are rated investment grade
quality by at least one nationally recognized statistical rating organization at
the time of entering


                                       27



into such transaction or whose creditworthiness is believed to be equivalent to
such rating. A buyer also will lose its investment and recover nothing should an
event of default occur. If an event of default were to occur, the value of the
reference obligation received by the seller, coupled with the periodic payments
previously received, may be less than the full notional value it pays to the
buyer, resulting in a loss of value to the fund. When the fund acts as a seller
of a credit default swap agreement it is exposed to the risks of a leveraged
transaction, since if an event of default occurs the seller must pay the buyer
the full notional value of the reference obligation.

CREDIT-LINKED NOTES

The fund may invest in credit-linked notes ("CLNs"), which are derivative
instruments. A CLN is a synthetic obligation between two or more parties where
the payment of principal and/or interest is based on the performance of some
obligation (a reference obligation). In addition to credit risk of the reference
obligations and interest rate risk, the buyer/seller of the CLN is subject to
counterparty risk.

FOREIGN CURRENCY SWAPS

Foreign currency swaps involve the exchange by the lenders, including the fund,
with another party (the "counterparty") of the right to receive the currency in
which the loans are denominated for the right to receive U.S. dollars. The fund
will enter into a foreign currency swap only if the outstanding debt obligations
of the counterparty are rated investment grade quality by at least one
nationally recognized statistical rating organization at the time of entering
into such transaction or whose creditworthiness is believed by the fund's
adviser to be equivalent to such rating. The amounts of U.S. dollar payments to
be received by the fund and the foreign currency payments to be received by the
counterparty are fixed at the time the swap arrangement is entered into.
Accordingly, the swap protects the fund from the fluctuations in exchange rates
and locks in the right to receive payments under the loan in a predetermined
amount of U.S. dollars. If there is a default by the counterparty, the fund will
have contractual remedies pursuant to the swap agreement; however, the U.S.
dollar value of the fund's right to receive foreign currency payments under the
obligation will be subject to fluctuations in the applicable exchange rate to
the extent that a replacement swap arrangement is unavailable or the fund is
unable to recover damages from the defaulting counterparty.

CROSS CURRENCY INTEREST RATE SWAP AGREEMENTS

Cross currency interest rate swap agreements combine features of currency swap
agreements and interest rate swap agreements. The cross currency interest rate
swaps in which the fund may enter generally will involve both the exchange of
currency and the payment of interest streams with reference to one currency
based on a specified index in exchange for receiving interest streams with
reference to the other currency. Such swaps may involve initial and final
exchanges that correspond to the agreed upon transaction amount. For example,
the payment stream on a specified amount of euro based on a European market
floating rate might be exchanged for a U.S. oriented floating rate on the same
principal amount converted into U.S. dollars.

LENDING OF PORTFOLIO SECURITIES

The fund may lend portfolio securities to registered broker-dealers or other
institutional investors deemed by Pioneer to be of good standing under
agreements which require that the loans be secured continuously by collateral in
cash, cash equivalents or U.S. Treasury bills maintained on a current basis at
an amount at least equal to the market value of the securities loaned. The fund
continues to receive the equivalent of the interest or dividends paid by the
issuer on the securities loaned as well as the benefit of an increase and the
detriment of any decrease in the market value of the securities loaned and would
also receive


                                       28



compensation based on investment of the collateral. The fund may
pay administrative and custodial fees in connection with loans of securities and
may pay a portion of the income or fee earned thereon to the borrower, lending
agent or other intermediary. The fund would not, however, have the right to vote
any securities having voting rights during the existence of the loan, but would
call the loan in anticipation of an important vote to be taken among holders of
the securities or of the giving or withholding of consent on a material matter
affecting the investment.

As with other extensions of credit, there are risks of delay in recovery or even
loss of rights in the collateral should the borrower of the securities fail
financially. The fund will lend portfolio securities only to firms that have
been approved in advance by the Board of Trustees, which will monitor the
creditworthiness of any such firms. At no time would the value of the securities
loaned exceed 33 1/3% of the value of the fund's total assets.


In the future, the Fund may engage in interfund securities and cash lending
transactions, in accordance with applicable rules and regulations, or, if
applicable, exemptive orders of the SEC, as then in effect. Through interfund
lending, the Fund may lend money to, and borrow money from, other Pioneer funds
for short-term purposes. As a borrower in an interfund lending transaction, the
Fund may have to borrow from a bank at a higher interest rate if an interfund
loan is called, which may occur on short notice, or not renewed. As a lender in
an interfund lending transaction, any delay in repayment to the Fund could
result in a lost investment opportunity or additional borrowing costs.


MORTGAGE DOLLAR ROLLS

The fund may enter into mortgage "dollar rolls" in which the fund sells
securities for delivery in the current month and simultaneously contracts with
the same counterparty to repurchase similar (same type, coupon and maturity),
but not identical securities on a specified future date. During the roll period,
the fund loses the right to receive principal and interest paid on the
securities sold. However, the fund would benefit to the extent of any difference
between the price received for the securities sold and the lower forward price
for the future purchase (often referred to as the "drop") or fee income plus the
interest earned on the cash proceeds of the securities sold until the settlement
date of the forward purchase. Unless such benefits exceed the income, capital
appreciation and gain or loss due to mortgage prepayments that would have been
realized on the securities sold as part of the mortgage dollar roll, the use of
this technique will diminish the investment performance of the fund compared
with what such performance would have been without the use of mortgage dollar
rolls. All cash proceeds will be invested in instruments that are permissible
investments for the fund. The fund will hold and maintain in a segregated
account until the settlement date cash or liquid securities in an amount equal
to its forward purchase price.

For financial reporting and tax purposes, the fund treats mortgage dollar rolls
as two separate transactions; one involving the purchase of a security and a
separate transaction involving a sale.

Mortgage dollar rolls involve certain risks including the following: if the
broker-dealer to whom the fund sells the security becomes insolvent, the fund's
right to purchase or repurchase the mortgage-related securities subject to the
mortgage dollar roll may be restricted and the instrument which the fund is
required to repurchase may be worth less than an instrument which the fund
originally held. Successful use of mortgage dollar rolls will depend upon
Pioneer's ability to manage its interest rate and mortgage prepayments exposure.
For these reasons, there is no assurance that mortgage dollar rolls can be
successfully employed.


                                       29



MONEY MARKET INSTRUMENTS

The fund may invest in short-term money market instruments including commercial
bank obligations and commercial paper. These instruments may be denominated in
both U.S. and, to a limited extent, foreign currency. The fund's investment in
commercial bank obligations include certificates of deposit ("CDs"), time
deposits ("TDs") and bankers' acceptances. Obligations of non-U.S. branches of
U.S. banks and of non-U.S. banks may be general obligations of the parent bank
in addition to the issuing bank, or may be limited by the terms of a specific
obligation and by government regulation. As with investment in non-U.S.
securities in general, investments in the obligations of non-U.S. branches of
U.S. banks and of non-U.S. banks may subject the fund to investment risks that
are different in some respects from those of investments in obligations of
domestic issuers.


The fund's investments in commercial paper consist of short-term (usually from 1
to 270 days) unsecured promissory notes issued by corporations in order to
finance their current operations. The fund may also invest in variable amount
master demand notes (which is a type of commercial paper) which represents a
direct borrowing arrangement involving periodically fluctuating rates of
interest under a letter agreement between a commercial paper issuer and an
institutional lender, pursuant to which the lender may determine to invest
varying amounts. Transfer of such notes is usually restricted by the issuer, and
there is no secondary trading market for such notes.


                             INVESTMENT RESTRICTIONS

FUNDAMENTAL INVESTMENT RESTRICTIONS. The fund has adopted certain fundamental
investment restrictions which, along with the fund's investment objective, may
not be changed without the affirmative vote of the holders of a "majority of the
outstanding voting securities" (as defined in the 1940 Act) of the fund.
Statements in italics are not part of the restriction. For this purpose, a
majority of the outstanding shares of the fund means the vote of the lesser of:

(i) 67% or more of the shares represented at a meeting, if the holders of more
than 50% of the outstanding shares are present in person or by proxy, or

(ii) more than 50% of the outstanding shares of the fund.

The fund may not:

(1) Issue senior securities, other than as permitted by the 1940 Act. Senior
securities that the fund may issue in accordance with the 1940 Act include
preferred shares, borrowing, futures, when-issued and delayed delivery
securities and forward foreign currency exchange transactions.

(2) Borrow money, other than as permitted by the 1940 Act. See "Leverage" in the
prospectus for a discussion of the extent that the fund may borrow in accordance
with the 1940 Act.

(3) Invest in real estate, except the fund may invest in securities of issuers
that invest in real estate or interests therein, securities that are secured by
real estate or interests therein, securities of real estate investment trusts,
mortgage-backed securities and other securities that represent a similar
indirect interest in real estate, and the fund may acquire real estate or
interests therein through exercising rights or remedies with regard to an
instrument.


                                       30



(4) Make loans, except that the fund may (i) lend portfolio securities, (ii)
enter into repurchase agreements, (iii) purchase all or a portion of an issue of
publicly distributed debt securities, loans, loan participation interests, bank
certificates of deposit, acceptances, debentures or other securities, whether or
not the purchase is made upon the original issuance of the securities, (iv)
participate in a credit facility whereby the fund may directly lend to and
borrow money from other affiliated funds to the extent permitted under the 1940
Act or an exemption therefrom and (v) make loans in any other manner consistent
with applicable law, as amended and interpreted or modified from time to time by
any regulatory authority having jurisdiction.

(5) Invest in commodities or commodity contracts, except that the fund may
invest in currency instruments and contracts and financial instruments and
contracts that might be deemed to be commodities and commodity contracts. A
futures contract, for example, may be deemed to be a commodity contract.

(6) Make any investment inconsistent with its classification as a diversified
open-end investment company under the 1940 Act. Currently, diversification means
that, with respect to 75% of its total assets, the fund may not purchase
securities of an issuer (other than the U.S. government, its agencies or
instrumentalities and securities of investment companies), if

     (a) such purchase would cause more than 5% of the fund's total assets,
     taken at market value, to be invested in the securities of such issuer, or

     (b) such purchase would at the time result in more than 10% of the
     outstanding voting securities of such issuer being held by the fund.

(7) Act as an underwriter, except insofar as the fund may be deemed to be an
underwriter in connection with the purchase or sale of its portfolio securities.


(8) Invest 25% or more of the value of its total assets in any one industry,
except that (a) the fund will invest more than 25% of its total assets in
securities or other instruments issued or structured by companies in the
financial services group of industries, such as banks, broker-dealers and
insurance and reinsurance companies, and (b) this limitation does not apply to
the purchase of obligations issued or guaranteed by the U.S. government, its
agencies or instrumentalities.


For purposes of investment restriction (4) above, in accordance with the current
requirements under the 1940 Act, at no time would the value of the securities
loaned, the value of repurchase agreement, and the value of all other
investments made under this restriction in the aggregate exceed 33 1/3 of the
value of the fund's total assets.

All other investment policies of the fund are considered non-fundamental and may
be changed by the Board of Trustees without prior approval of the fund's
outstanding voting shares.

The fund has not adopted a fundamental policy prohibiting or limiting the fund's
use of short sales, purchases on margin and the writing of put and call options.
The fund is subject, however, to the limitations on its use of these investments
under the 1940 Act and the rules and interpretive positions of the SEC under the
1940 Act. Under current law, the fund may not purchase securities on margin.
Certain other non-fundamental investment policies are included in the prospectus
under "Investment objectives


                                       31



and Principal investment strategies" and this statement of additional
information under "Investment objectives and policies."

The fund intends to apply for ratings for the preferred shares from one or more
nationally recognized statistical rating organizations. In order to obtain and
maintain the required ratings, the fund will be required to comply with
investment quality, diversification and other guidelines established by such
rating agency or agencies. The fund does not anticipate that such guidelines
would have a material adverse effect on the fund's holders of common shares or
its ability to achieve its investment objectives. The fund presently anticipates
that any preferred shares that it intends to issue would be initially given the
highest ratings by such rating agency or agencies, but no assurance can be given
that such ratings will be obtained. No minimum rating is required for the
issuance of preferred shares by the fund.

*    Mr. Cogan and Mr. Kingsbury are Interested Trustees because each is an
     officer or director of the fund's investment adviser and certain of its
     affiliates.

The outstanding capital stock of Pioneer is indirectly wholly owned by
UniCredito Italiano S.p.A. ("UniCredito Italiano"), one of the largest banking
groups in Italy. Pioneer, the fund's investment adviser, provides investment
management and financial services to mutual funds, institutional and other
clients.

The fund's Board of Trustees consists of nine members and is divided into three
classes:

Class I:   Margaret B.W. Graham, Daniel K. Kingsbury and John Winthrop ("Class I
           Trustees")
Class II:  Mary K. Bush, Thomas J. Perna and Marguerite Piret ("Class II
           Trustees")
Class III: David R. Bock, John F. Cogan, Jr., and Stephen K. West ("Class III
           Trustees")


                                       37


The term of one class expires each year commencing with the first annual meeting
following this public offering and no term shall continue for more than three
years after the applicable election. The term of the Class I Trustees shall
expire at the first annual shareholder meeting following this public offering,
the term of the Class II Trustees expire at the second annual shareholder
meeting, and the terms of the Class III Trustees shall expire at the third
annual shareholder meeting. Subsequently, each class of Trustees will stand for
election at the conclusion of its respective term. Such classification may
prevent replacement of a majority of the Trustees for up to a two-year period.

POLICY ADMINISTRATION

The Board of Trustees has adopted a charter for the Audit Committee. In
accordance with its charter, the purposes of the Audit Committee are to:

-    act as a liaison between the fund's independent registered public
     accounting firm and the full Board of Trustees of the fund;

-    discuss with the fund's independent registered public accounting firm their
     judgments about the quality of the fund's accounting principles and
     underlying estimates as applied in the fund's financial reporting;

-    review and assess the renewal materials of all related party contracts and
     agreements, including management advisory agreements, underwriting
     contracts, administration agreements, distribution contracts, and transfer
     agency contracts, among any other instruments and agreements that may be
     appropriate from time to time;

-    review and approve insurance coverage and allocations of premiums between
     the management and the fund and among the Pioneer Funds;

-    review and approve expenses under the administration agreement between
     Pioneer and the fund and allocations of such expenses among the Pioneer
     Funds; and


                                       38



-    receive on a periodic basis a formal written statement delineating all
     relationships between the independent registered public accounting firm and
     the fund or Pioneer; to actively engage in a dialogue with the independent
     registered public accounting firm with respect to any disclosed
     relationships or services that may impact the objectivity and independence
     of the firm; and to recommend that the Trustees take appropriate action in
     response to the independent registered public accounting firm's report to
     satisfy itself of the firm's independence.

The Nominating Committee reviews the qualifications of any candidate recommended
by the Independent Trustees to serve as an Independent Trustee and makes a
recommendation regarding that person's qualifications. The Committee does not
accept nominations from shareholders.

The Valuation Committee reviews the valuation assigned to certain securities by
Pioneer in accordance with the fund's valuation procedures.

The Policy Administration Committee reviews the implementation of certain of the
fund's administrative policies and procedures.

The Independent Trustees Committee reviews the fund's management contract and
other related party contracts annually and is also responsible for any other
action required to be taken, under the 1940 Act, by the Independent Trustees
acting alone.

The fund's Agreement and Declaration of Trust provides that the fund will
indemnify the Trustees and officers against liabilities and expenses incurred in
connection with any litigation in which they may be involved because of their
offices with the fund, unless it is determined in the manner specified in the
Agreement and Declaration of Trust that they have not acted in good faith in the
reasonable belief that their actions were in the best interests of the fund or
that such indemnification would relieve any officer or Trustee of any liability
to the fund or its shareholders by reason of willful misfeasance, bad faith,
gross negligence or reckless disregard of his or her duties.

COMPENSATION OF OFFICERS AND TRUSTEES

The fund pays no salaries or compensation to any of its officers. The Pioneer
Funds, including the fund, compensate their Trustees. The Independent Trustees
review and set their compensation annually, taking into consideration the
committee and other responsibilities assigned to specific Trustees. The table
under "Annual Fees, Expense and Other Information-Compensation of Officers and
Trustees" sets forth the compensation paid to each of the Trustees. The
compensation paid to the Trustees is then allocated among the funds as follows:

-    each fund with assets less than $250 million pays each Independent Trustees
     an annual fee of $1,000.

-    the remaining compensation of the Independent Trustees is allocated to each
     fund with assets greater than $250 million based on the fund's net assets.

-    the Interested Trustees receive an annual fee of $500 from each fund,
     except in the case of funds with net assets of $50 million or less, which
     pay each Interested Trustee an annual fee of $200. Pioneer reimburses the
     funds for the fees paid to the Interested Trustees.

The following table sets forth certain information with respect to the
compensation paid to each Trustee by the fund and the Pioneer Funds as a group.
Compensation from the fund is for the current calendar year and is estimated.
Total compensation from the Pioneer Funds as a group is for the calendar year
ended December 31, 2006.

statements below:

-    the immediate family members of any person are their spouse, children in
     the person's household (including step and adoptive children) and any
     dependent of the person.

-    an entity in a control relationship means any person who controls, is
     controlled by or is under common control with the named person. For
     example, UniCredito Italiano is an entity that is in a control relationship

     the definition of an investment company pursuant to Sections 3(c)(1) or
     3(c)(7) of the 1940 Act, for which Pioneer or any of its affiliates act as

CODE OF ETHICS. The fund's Board of Trustees approved a code of ethics under
Rule 17j-1 under the 1940 Act that covers the fund, Pioneer and certain of
Pioneer's affiliates. The code of ethics establishes procedures for personal
investing and restricts certain transactions. Employees subject to the code of
ethics may invest in securities for their personal investment accounts,
including securities that may be purchased or held by the fund.

INVESTMENT ADVISER AND SUBADVISER


INVESTMENT ADVISER. The fund has contracted with Pioneer to act as its
investment adviser. Pioneer is an indirect, wholly owned subsidiary of
UniCredito Italiano. Pioneer is an indirect, majority owned subsidiary of
UniCredito. Pioneer is part of the global asset management group providing
investment management and financial services to mutual funds, institutional and
other clients. As of March 31, 2006, assets under management were approximately
$310 billion worldwide, including over $81 billion in assets under management by
Pioneer. Certain Trustees or officers of the trust are also directors and/or
officers of certain of UniCredito Italiano's subsidiaries (see management
biographies above). Pioneer has entered into an agreement with its affiliate,
Pioneer Investment Management Limited ("PIML"), pursuant to which PIML provides
certain services and personnel to Pioneer.



                                       42



As the fund's investment adviser, Pioneer is responsible for managing the fund's
overall investment program, supervising the Subadviser's investments in
event-linked bonds on behalf of the fund, supervising the fund's overall
compliance program and providing for the general management of the business
affairs of the fund. Pioneer and the Subadviser provide the fund with investment
research, advice and supervision and furnish an investment program for the fund
consistent with the fund's investment objectives and policies, subject to the
supervision of the fund's Trustees. Pioneer and the Subadviser determine what
portfolio securities will be purchased or sold, arrange for the placing of
orders for the purchase or sale of portfolio securities, select brokers or
dealers to place those orders, maintains books and records with respect to the
fund's securities transactions, and report to the Trustees on the fund's
investments and performance.

SUBADVISER. Pioneer has engaged Montpelier Capital Advisors, Ltd. to act as the
fund's investment subadviser with respect to the fund's investments in
event-linked bonds. The Subadviser, under the supervision of Pioneer, is
responsible for the day-to-day management of the fund's portfolio of investments
in event-linked bonds. The Subadviser also advises Pioneer as to the relative
value of investments in event-linked bonds, compared to other sectors of the
fixed income securities markets.


ADMINISTRATOR. The fund has entered into an administration agreement with the
Pioneer, pursuant to which Pioneer will provide certain administrative and
accounting services to the fund. Pioneer has appointed Princeton Administrators,
LLC as the sub-administrator to the fund to perform certain of Pioneer's
administration and accounts obligations to the fund. Under the administration
agreements, the fund will pay Pioneer a monthly fee equal to 0.07% of the fund's
average daily managed assets up to $500 million and 0.03% for average daily
managed assets in excess of $500 million. Pioneer and not the fund, is
responsible for paying the fees of Princeton Administrators, LLC.


Pursuant to a separate agreement, the fund may compensate the Pioneer for
providing certain legal and accounting services at the annual rate of 0.0175% of
the fund's average daily managed assets.

TRANSFER AGENT. PIMSS has entered into a transfer agency agreement with the fund
pursuant to which PIMSS provides certain transfer agency services to the fund.
Under the transfer agency agreement, the fund will reimburse PIMSS for its cost
of providing such services to the fund. PIMSS has retained American Stock
Transfer & Trust Company to provide sub-transfer agent, sub-registrar and
sub-dividend dispersing agent services for the fund. The fund will pay PIMSS a
fee for such services. The transfer agency agreement may be terminated by the
fund or PIMSS (without penalty) at any time upon not less than 60 days' prior
written notice to the other party to the agreement.

DIRECT REGISTRATION OF FUND SHARES. Through American Stock & Transfer Company,
the fund has made its common shares eligible for inclusion in the direct
registration system ("DRS") administered by The Depository Trust Company
("DTC"), wherein American Stock & Transfer Company will process transfers of
common shares utilizing DTC's Profile Modification System.

CUSTODIAN. Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts
02109, is the custodian of the fund's assets. The custodian's responsibilities
include safekeeping and controlling the fund's cash and securities, handling the
receipt and delivery of securities, and collecting interest and dividends on the
fund's investments.

MANAGEMENT CONTRACT. Under the management contract, the fund will pay to Pioneer
monthly, as compensation for the services rendered and expenses paid by it, a
fee equal on an annual basis to 0.85% of the fund's average daily managed
assets. "Managed assets" means the total assets of the fund, including any form
of investment leverage, minus all accrued expenses incurred in the normal course
of operations, but not excluding any liabilities or obligations attributable to
investment leverage obtained


                                       43



through (i) indebtedness of any type (including, without limitation, borrowing
through a credit facility or the issuance of debt securities), (ii) the issuance
of preferred stock or other similar preference securities, (iii) the
reinvestment of collateral received for securities loaned in accordance with the
fund's investment objectives and policies and/or (iv) any other means. The
liquidation preference on any preferred shares is not a liability. The fund's
average daily managed assets are determined for the purpose of calculating the
advisory fee by taking the average of all the daily determinations of total
assets during a given calendar month. The fee is payable for each calendar month
as soon as practicable after the end of that month.

Under the terms of the management contract, Pioneer pays all of the operating
expenses, including executive salaries and the rental of office space, relating
to its services for the fund, with the exception of the following, which are to
be paid by the fund: (a) charges and expenses for fund accounting, pricing and
appraisal services and related overhead, including, to the extent such services
are performed by personnel of Pioneer or its affiliates, office space and
facilities and personnel compensation, training and benefits; (b) the charges
and expenses of auditors; (c) the charges and expenses of any administrator,
custodian, transfer agent, plan agent, dividend disbursing agent, registrar or
any other agent appointed by the fund; (d) issue and transfer taxes chargeable
to the fund in connection with securities transactions to which the fund is a
party; (e) insurance premiums, interest charges, expenses in connection with any
preferred shares, a portion of the offering expenses, dues and fees for
membership in trade associations and all taxes and corporate fees payable by the
fund to federal, state or other governmental agencies; (f) fees and expenses
involved in registering and maintaining registrations of the fund and/or its
shares with federal regulatory agencies, state or blue sky securities agencies
and foreign jurisdictions, including the preparation of prospectuses and
statements of additional information for filing with such regulatory
authorities; (g) all expenses of shareholders' and Trustees' meetings and of
preparing, printing and distributing prospectuses, notices, proxy statements and
all reports to shareholders and to governmental agencies; (h) charges and
expenses of legal counsel to the fund and the Board of Trustees; (i)
compensation of those Trustees of the fund who are not affiliated with or
interested persons of Pioneer or the fund (other than as Trustees); (j) the cost
of preparing and printing share certificates; (k) interest on borrowed money, if
any; (l) the fees and other expenses of listing the fund's shares on the
American Stock Exchange or any other national stock exchange; and (m) any other
expense that the fund, Pioneer or any other agent of the fund may incur (I) as a
result of a change in the law or regulations, (II) as a result of a mandate from
the Board of Trustees with associated costs of a character generally assumed by
similarly structured investment companies or (III) that is similar to the
expenses listed above, and that is approved by the Board of Trustees (including
a majority of the Trustees who are not affiliates of Pioneer) as being an
appropriate expense of the fund. In addition, the fund will pay all brokers' and
underwriting commissions or other fees chargeable to the fund in connection with
securities transactions to which the fund is a party or the origination of any
floating rate loan in which the fund invests.

The Trustees' approval of and the terms, continuance and termination of the
management contract are governed by the 1940 Act and the Investment Advisers Act
of 1940, as applicable. Pursuant to the management contract, Pioneer will not be
liable for any error of judgment or mistake of law or for any loss sustained by
reason of the adoption of any investment policy or the purchase, sale or
retention of any securities on the recommendation of Pioneer. Pioneer, however,
is not protected against liability by reason of willful misfeasance, bad faith
or gross negligence in the performance of its duties or by reason of its
reckless disregard of its obligations and duties under the management contract.

SUBADVISORY CONTRACT. Montpelier Capital Advisors, Ltd. serves as the fund's
investment subadviser. Under the terms of the subadvisory agreement (the
"Subadvisory Agreement") between the Pioneer and the Subadviser, the Subadviser
will act as a sub-investment adviser with respect to that portion of the fund's
portfolio invested in event-linked bonds ("Sub-Advised Assets"). In such
capacity, the Subadviser shall, with respect to Sub-Advised Assets, and subject
to the supervision of Pioneer and the fund's Board, among other things (a)
regularly provide the fund with investment research, advice and supervision and


                                       44



furnish continuously an investment program for the fund; (b) subject to the
supervision of Pioneer, manage the investment and reinvestment of the fund's
Sub-Advised Assets; (c) keep the fund and Pioneer informed of developments
materially affecting the fund's Sub-Advised Assets, including market valuations
and pricing information on fund holdings to Pioneer and/or the fund's pricing
agent as necessary to make any fair value determinations; (c) comply with the
provisions of the fund's Agreement and Declaration of Trust and By-Laws, the
1940 Act, the Investment Advisers Act of 1940, as amended, and the investment
objectives, policies and restrictions of the fund; (d) not take any action to
cause the fund to fail to comply with the requirements of Subchapter M of the
United States Internal Revenue Code of 1986, as amended (the "Code"), for
qualification as a regulated investment company; (e) comply with any policies,
guidelines, procedures and instructions as Pioneer may from time to time
establish; (f) be responsible for voting proxies and acting on other corporate
actions if instructed to do so by the Board of Trustees or Pioneer; (g) maintain
separate books and detailed records of all matters pertaining to the portion of
the Sub-Advised Assets required by Rule 31a-1 under the 1940 Act relating to its
responsibilities provided under the Subadvisory Agreement with respect to the
fund; and (h) furnish reports to the Trustees and Pioneer.

Under the terms of the Subadvisory Agreement, for its services the Subadviser is
entitled to a subadvisory fee from Pioneer at an annual rate of 0.80% the fund's
average daily Sub-Advised Assets; provided, however, that such fee shall in no
event be less than 0.15% of the fund's average daily managed assets. The fee
will be paid monthly in arrears. The fund does not pay a fee to the Subadviser.

POTENTIAL CONFLICTS OF INTEREST. The fund's investment adviser is Pioneer, which
also serves as investment adviser to other Pioneer mutual funds and other
accounts with investment objectives identical or similar to those of the fund.
Securities frequently meet the investment objectives of the fund, the other
Pioneer mutual funds and such other accounts. In such cases, the decision to
recommend a purchase to one fund or account rather than another is based on a
number of factors. The determining factors in most cases are the amount of
securities of the issuer then outstanding, the value of those securities and the
market for them. Other factors considered in the investment recommendations
include other investments which each fund or account presently has in a
particular industry and the availability of investment funds in each fund or
account.

It is possible that at times identical securities will be held by more than one
fund and/or account. However, positions in the same issue may vary and the
length of time that any fund or account may choose to hold its investment in the
same issue may likewise vary. To the extent that more than one of the Pioneer
mutual funds or a private account managed by Pioneer seeks to acquire the same
security at about the same time, the fund may not be able to acquire as large a
position in such security as it desires or it may have to pay a higher price for
the security. Similarly, the fund may not be able to obtain as large an
execution of an order to sell or as high a price for any particular portfolio
security if Pioneer decides to sell on behalf of another account the same
portfolio security at the same time. On the other hand, if the same securities
are bought or sold at the same time by more than one fund or account, the
resulting participation in volume transactions could produce better executions
for the fund. In the event more than one account purchases or sells the same
security on a given date, the purchases and sales will normally be made as
nearly as practicable on a pro rata basis in proportion to the amounts desired
to be purchased or sold by each account. Although the other Pioneer mutual funds
may have the same or similar investment objectives and policies as the fund,
their portfolios do not generally consist of the same investments as the fund or
each other, and their performance results are likely to differ from those of the
fund.

PERSONAL SECURITIES TRANSACTIONS. The fund, Pioneer and PFD have adopted a code
of ethics under Rule 17j-1 under the 1940 Act which is applicable to officers,
trustees/directors and designated employees of Pioneer and PIML. The code
permits such persons to engage in personal securities transactions for their own
accounts, including securities that may be purchased or held by the fund, and is
designed to prescribe


                                       45


means reasonably necessary to prevent conflicts of interest from arising in
connection with personal securities transactions. The code is on public file
with and available from the SEC.

POTENTIAL CONFLICTS OF INTEREST. When a portfolio manager is responsible for the
management of more than one account, the potential arises for the portfolio
manager to favor one account over another. The principal types of potential
conflicts of interest that may arise are discussed below. For the reasons
outlined below, Pioneer does not believe that any material conflicts are likely
to arise out of a portfolio manager's responsibility for the management of the
fund as well as one or more other accounts. Although Pioneer has adopted
procedures that it believes are reasonably designed to detect and prevent
violations of the federal securities laws and to mitigate the potential for
conflicts of interest to affect its portfolio management decisions, there can be
no assurance that all conflicts will be identified or that all procedures


                                       47



will be effective in mitigating the potential for such risks. Generally, the
risks of such conflicts of interests are increased to the extent that a
portfolio manager has a financial incentive to favor one account over another.
Pioneer has structured its compensation arrangements in a manner that is
intended to limit such potential for conflicts of interests. See "Compensation
of Portfolio Managers" below.

     -    A portfolio manager could favor one account over another in allocating
          new investment opportunities that have limited supply, such as initial
          public offerings and private placements. If, for example, an initial
          public offering that was expected to appreciate in value significantly
          shortly after the offering was allocated to a single account, that
          account may be expected to have better investment performance than
          other accounts that did not receive an allocation of the initial
          public offering. Generally, investments for which there is limited
          availability are allocated based upon a range of factors including
          available cash and consistency with the accounts' investment
          objectives and policies. This allocation methodology necessarily
          involves some subjective elements but is intended over time to treat
          each client in an equitable and fair manner. Generally, the investment
          opportunity is allocated among participating accounts on a pro rata
          basis. Although Pioneer believes that its practices are reasonably
          designed to treat each client in an equitable and fair manner, there
          may be instances where a fund may not participate, or may participate
          to a lesser degree than other clients, in the allocation of an
          investment opportunity.

     -    A portfolio manager could favor one account over another in the order
          in which trades for the accounts are placed. If a portfolio manager
          determines to purchase a security for more than one account in an
          aggregate amount that may influence the market price of the security,
          accounts that purchased or sold the security first may receive a more
          favorable price than accounts that made subsequent transactions. The
          less liquid the market for the security or the greater the percentage
          that the proposed aggregate purchases or sales represent of average
          daily trading volume, the greater the potential for accounts that make
          subsequent purchases or sales to receive a less favorable price. When
          a portfolio manager intends to trade the same security on the same day
          for more than one account, the trades typically are "bunched," which
          means that the trades for the individual accounts are aggregated and
          each account receives the same price. There are some types of accounts
          as to which bunching may not be possible for contractual reasons (such
          as directed brokerage arrangements). Circumstances may also arise
          where the trader believes that bunching the orders may not result in
          the best possible price. Where those accounts or circumstances are
          involved, Pioneer will place the order in a manner intended to result
          in as favorable a price as possible for such client.

     -    A portfolio manager could favor an account if the portfolio manager's
          compensation is tied to the performance of that account to a greater
          degree than other accounts managed by the portfolio manager. If, for
          example, the portfolio manager receives a bonus based upon the
          performance of certain accounts relative to a benchmark while other
          accounts are disregarded for this purpose, the portfolio manager will
          have a financial incentive to seek to have the accounts that determine
          the portfolio manager's bonus achieve the best possible performance to
          the possible detriment of other accounts. Similarly, if Pioneer
          receives a performance-based advisory fee, the portfolio manager may
          favor that account, whether or not the performance of that account
          directly determines the portfolio manager's compensation.

     -    A portfolio manager could favor an account if the portfolio manager
          has a beneficial interest in the account, in order to benefit a large
          client or to compensate a client that had poor returns. For example,
          if the portfolio manager held an interest in an investment partnership
          that was one of the accounts managed by the portfolio manager, the
          portfolio manager would have an economic incentive to favor the
          account in which the portfolio manager held an interest.


                                       48



     -    If the different accounts have materially and potentially conflicting
          investment objectives or strategies, a conflict of interest could
          arise. For example, if a portfolio manager purchases a security for
          one account and sells the same security for another account, such
          trading pattern may disadvantage either the account that is long or
          short. In making portfolio manager assignments, Pioneer seeks to avoid
          such potentially conflicting situations. However, where a portfolio
          manager is responsible for accounts with differing investment
          objectives and policies, it is possible that the portfolio manager
          will conclude that it is in the best interest of one account to sell a
          portfolio security while another account continues to hold or increase
          the holding in such security.


POTENTIAL CONFLICTS OF INTEREST FOR SUBADVISER. A potential conflict of interest
could arise in the event that Montpelier Re Ltd., the subadviser's parent
company, has an interest in investing in an event-linked bond that is also a
suitable investment for the fund. The subadviser seeks to avoid this potential
conflict by communicating any such potential conflict of interest in advance to
Pioneer. In all cases, the subadviser will provide Pioneer with information
relating to Montpelier Re Ltd.'s or any affiliate's interest (in buying, selling
or issuing) a specific event-linked bond, prior to consummating any transaction
on behalf of its affiliates. In addition, the subadviser will provide Pioneer
with a report listing all event linked bond transactions and sales on at least a
quarterly basis.



COMPENSATION OF PORTFOLIO MANAGERS. Pioneer has adopted a system of compensation
for portfolio managers that seeks to align the financial interests of the
portfolio managers with those of shareholders of the accounts (including Pioneer
funds) the portfolio managers manage, as well as with the financial performance
of Pioneer. The compensation program for all Pioneer portfolio managers includes
a base salary (determined by the rank and tenure of the employee) and an annual
bonus program, as well as customary benefits that are offered generally to all
full-time employees. Base compensation is fixed and normally reevaluated on an
annual basis. Pioneer seeks to set base compensation at market rates, taking
into account the experience and responsibilities of the portfolio manager. The
bonus plan is intended to provide a competitive level of annual bonus
compensation that is tied to the portfolio manager achieving superior investment
performance and align the interests of the investment professional with those of
shareholders, as well as with the financial performance of Pioneer. Any bonus
under the plan is completely discretionary, with a maximum annual bonus that may
be in excess of base salary. The annual bonus is based upon a combination of the
following factors:



     -    Quantitative Investment Performance. The quantitative investment
          performance calculation is based on pre-tax investment performance of
          all of the accounts managed by the portfolio manager (which includes
          the fund and any other accounts managed by the portfolio manager) over
          a one-year period (20% weighting) and four-year period (80%
          weighting), measured for periods ending on December 31. The accounts,
          which include the fund, are ranked against a group of mutual funds
          with similar investment objectives and investment focus (60%) and a
          broad-based securities market index measuring the performance of the
          same type of securities in which the accounts invest (40%), which, in
          the case of the fund, is the Merrill Lynch Global High Yield and
          Emerging Markets Plus Index and the Credit Suisse Leveraged Loan
          Index. As a result of these two benchmarks, the performance of the
          portfolio manager for compensation purposes is measured against the
          criteria that are relevant to the portfolio manager's competitive
          universe.



     -    Qualitative Performance. The qualitative performance component with
          respect to all of the accounts managed by the portfolio manager
          includes objectives such as effectiveness in the areas of teamwork,
          leadership, communications and marketing, that are mutually
          established and evaluated by each portfolio manager and management.


     -    Pioneer Results and Business Line Results. Pioneer's financial
          performance, as well as the investment performance of its investment
          management group, affect a portfolio manager's actual bonus by a
          leverage factor of plus or minus (+/-) a predetermined percentage.


The quantitative and qualitative performance components comprise 80% and 20%,
respectively, of the



                                       49




overall bonus calculation (on a pre-adjustment basis). A portion of the annual
bonus is deferred for a specified period and may be invested in one or more
Pioneer funds.



Certain portfolio managers may participate in other programs designed to reward
and retain key contributors. Senior executives or other key employees may be
granted performance units based on the stock price performance of UniCredito
Italiano and the financial performance of Pioneer Global Asset Management
S.p.A., which are affiliates of Pioneer. Portfolio managers also may participate
in a deferred compensation program, whereby deferred amounts are invested in one
or more Pioneer funds.


COMPENSATION OF THE SUBADVISER'S PORTFOLIO MANAGERS.

The subadviser's compensation program consists of three components: (i) base
salary and benefits, (ii) annual cash bonus, and (iii) long-term equity
incentive awards. The principal benefit plans and arrangements that are offered
include housing allowances, a deferred compensation plan, retirement benefits,
medical and dental insurance and travel. The combination of components for each
portfolio manager is set by a committee. The subadviser's compensation
arrangements with its portfolio managers are determined on the basis of the
portfolio manager's overall services to the subadviser and its affiliates and
not on the basis of a specific fund or other accounts, if any, managed by the
portfolio manager.

BASE SALARY AND BENEFITS. Each portfolio manager's base salary and benefits are
set by a committee in consultation with the Chief Executive Officer by reference
to the nature and demands of the past, the knowledge, skill and experience of
the individual and the state of the market for recruitment into comparable
positions. The subadviser seeks to set base compensation at market rates based
on industry surveys.

ANNUAL CASH BONUS. The subadviser pays annual cash bonuses in order to reward
short-term performance. Each year, the committee reviews and adopts an annual
cash bonus plan on behalf of the subadviser and its affiliates. Under the annual
bonus plan, the maximum bonus opportunity, expressed as a percentage of salary,
and related performance criteria are set in advance for each by the committee.
The final value of the bonus is derived from a sliding scale operating around a
central percentage target return on allocated capital.

LONG-TERM INCENTIVE AWARDS. At the discretion of the committee, incentive
awards, the value of which is based on and paid in the parent company's common
shares, may be made to all eligible plan participants. Generally, the awards are
granted annually in advance of the commencement of a three-year performance
period. Incentive awards that may be granted consist of share appreciation
rights, performance shares and restricted share units. Each type of award gives
a plan participant the right to receive a payment in cash, common shares or a
combination of both, including dividend equivalents in the case of restricted
share units, at the discretion of the committee.

The fund is newly organized and had not commenced operations as of April 30,
2006.

                             PORTFOLIO TRANSACTIONS

All orders for the purchase or sale of portfolio securities are placed on behalf
of the fund by Pioneer and/or the Subadviser pursuant to authority contained in
the fund's management contract and the subadvisory contract. Securities
purchased and sold on behalf of the fund normally will be traded in the over-the
counter market on a net basis (i.e. without commission) through dealers acting
for their own account and not as brokers or otherwise through transactions
directly with the issuer of the instrument. The cost of securities purchased
from underwriters includes an underwriter's commission or concession, and the
prices at which securities are purchased and sold from and to dealers include a
dealer's markup or markdown. Pioneer and the Subadviser normally seek to deal
directly with the primary market makers unless, in its opinion, better prices
are available elsewhere. Pioneer and the Subadviser seek 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 and the Subadviser consider
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 and the Subadviser may select broker-dealers that provide brokerage
and/or research services to the fund and/or other investment companies or other
accounts managed by Pioneer or the Subadviser over which it or its affiliates
exercise investment discretion. In addition, consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended ("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,


                                       51



because many transactions on behalf of the 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 or the
Subadviser in rendering investment management services to the fund as well as
other investment companies or other accounts managed by Pioneer or the
Subadviser, although not all such research may be useful to the fund.
Conversely, such information provided by brokers or dealers who have executed
transaction orders on behalf of such other accounts may be useful to Pioneer and
the Subadviser in carrying out its obligations to the fund. The receipt of such
research has not reduced Pioneer's or the Subadviser's normal independent
research activities; however, it enables Pioneer and the Subadviser to avoid the
additional expenses which might otherwise be incurred if it were to attempt to
develop comparable information through its own staff.


The fund may participate in third-party brokerage and/or expense offset
arrangements to reduce the fund's total operating expenses. Pursuant to
third-party brokerage arrangements, the fund may incur lower expenses by
directing brokerage to third-party broker-dealers which have agreed to use part
of their commission to pay the fund's fees to service providers unaffiliated
with Pioneer or the Subadviser, or other expenses. Since the commissions paid to
the third party brokers reflect a commission cost that the fund would generally
expect to incur on its brokerage transactions but not necessarily the lowest
possible commission, this arrangement is intended to reduce the fund's operating
expenses without increasing the cost of its brokerage commissions. Since use of
such directed brokerage is subject to the requirement to achieve best execution
in connection with the fund's brokerage transactions, there can be no assurance
that such arrangements will be utilized. Pursuant to expense offset
arrangements, the fund may incur lower transfer agency expenses due to interest
earned on cash held with the transfer agent.

                          REPURCHASE OF COMMON SHARES

The fund is a closed-end investment company and as such its shareholders will
not have the right to cause the fund to redeem their shares. Instead, the fund's
common shares will trade in the open market at a price that will be a function
of several factors, including dividend levels (which are in turn affected by
expenses), net asset value, call protection, dividend stability, relative demand
for and supply of such shares in the market, general market and economic
conditions and other factors. Shares of closed-end funds frequently trade at a
discount to their net asset value. Common shares of closed-end investment
companies have during some periods traded at prices higher than their net asset
value (at a "premium") and during other periods traded at prices lower than
their net asset value (at a "discount"). This is in part because the market
price reflects the dividend yield on the common shares. When the yield on the
net asset value per share is higher than yields generally available in the
market for comparable securities, the market price will tend to reflect this by
trading higher than the net asset value per share to adjust the yield to a
comparable market rate. To the extent the common shares do trade at a discount,
the fund's Board of Trustees may from time to time engage in open market
repurchases or tender offers for shares after balancing the benefit to
shareholders of the increase in the net asset value per share resulting from
such purchases against the decrease in the assets of the fund and potential
increase in the expense ratio of expenses to assets of the fund and consequent
reduction in yield. The Board of Trustees believes that in addition to the
beneficial effects described above, any such purchases or tender offers may
result in the temporary narrowing of any discount but will not have any
long-term effect on the level of any discount.


                                       52



At any time when the fund has outstanding preferred shares, the fund may not
purchase, redeem or otherwise acquire any of its common shares unless (1) all
accrued preferred shares dividends have been paid and (2) at the time of such
purchase, redemption or acquisition, the net asset value of the fund's portfolio
(determined after deducting the acquisition price of the common shares) is at
least 200% of the liquidation value of the outstanding preferred shares
(expected to equal the original purchase price per share plus any accrued and
unpaid dividends thereon). Any service fees incurred in connection with any
tender offer made by the fund will be borne by the fund and will not reduce the
stated consideration to be paid to tendering shareholders.

Subject to its investment restrictions, the fund may borrow to finance the
repurchase of shares or to make a tender offer. Interest on any borrowings to
finance share repurchase transactions or the accumulation of cash by the fund in
anticipation of share repurchases or tenders will reduce the fund's net income.
Any share repurchase, tender offer or borrowing that might be approved by the
fund's Board of Trustees would have to comply with the Exchange Act, the 1940
Act and the rules and regulations thereunder.


Although the decision to take action in response to a discount from net asset
value will be made by the Board of Trustees at the time it considers such issue,
it is the board's present policy, which may be changed by the Board of Trustees,
not to authorize repurchases of common shares or a tender offer for such shares
if: (1) such transactions, if consummated, would (a) result in the delisting of
the common shares from the American Stock Exchange, or (b) impair the fund's
status as a regulated investment company under the Code (which would make the
fund a taxable entity, causing the fund's income to be taxed at the corporate
level in addition to the taxation of shareholders who receive dividends from the
fund) or as a registered closed-end investment company under the 1940 Act; (2)
the fund would not be able to liquidate portfolio securities in an orderly
manner and consistent with the fund's investment objectives and policies in
order to repurchase shares; or (3) there is, in the Board's judgment, any (a)
material legal action or proceeding instituted or threatened challenging such
transactions or otherwise materially adversely affecting the fund, (b) general
suspension of or limitation on prices for trading securities on the American
Stock Exchange, (c) declaration of a banking moratorium by federal or state
authorities or any suspension of payment by United States or New York banks, (d)
material limitation affecting the fund or the issuers of its portfolio
securities by federal or state authorities on the extension of credit by lending
institutions or on the exchange of foreign currency, (e) commencement of war,
armed hostilities or other international or national calamity directly or
indirectly involving the United States or (f) other event or condition that
would have a material adverse effect (including any adverse tax effect) on the
fund or its shareholders if shares were repurchased. The Board of Trustees may
in the future modify these conditions in light of experience.


The repurchase by the fund of its shares at prices below net asset value will
result in an increase in the net asset value of those shares that remain
outstanding. However, there can be no assurance that share repurchases or tender
offers at or below net asset value will result in the fund's shares trading at a
price equal to their net asset value. Nevertheless, the fact that the fund's
shares may be the subject of repurchase or tender offers from time to time, or
that the fund may be converted to an open-end investment company, may reduce any
spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the fund of its common shares will decrease the
fund's total assets, which would likely have the effect of increasing the fund's
expense ratio. Any purchase by the fund of its common shares at a time when
preferred shares are outstanding will increase the leverage applicable to the
outstanding common shares then remaining.

Before deciding whether to take any action if the common shares trade below net
asset value, the fund's Board of Trustees would likely consider all relevant
factors, including the extent and duration of the


                                       53



discount, the liquidity of the fund's portfolio, the impact of any action that
might be taken on the fund or its shareholders and market considerations. Based
on these considerations, even if the fund's shares should trade at a discount,
the Board of Trustees may determine that, in the interest of the fund and its
shareholders, no action should be taken.

                           FEDERAL INCOME TAX MATTERS

The following is a summary discussion of certain U.S. federal income tax
consequences that may be relevant to a shareholder acquiring, holding and
disposing of common shares of the fund. This discussion addresses only U.S.
federal income tax consequences to U.S. shareholders who hold their shares as
capital assets and does not address all of the U.S. federal income tax
consequences that may be relevant to particular shareholders in light of their
individual circumstances. This discussion also does not address the tax
consequences to shareholders who are subject to special rules, including,
without limitation, banks and financial institutions, insurance companies,
dealers in securities, foreign shareholders, tax-exempt or tax-deferred plans,
accounts, or entities, or investors who engage in constructive sale or
conversion transactions. In addition, the discussion does not address state,
local or foreign tax consequences, and it does not address any tax consequences
other than U.S. federal income tax consequences. The discussion reflects
applicable tax laws of the United States as of the date of this statement of
additional information, which tax laws may be changed or subject to new
interpretations by the courts, Treasury or the Internal Revenue Service (the
"IRS") retroactively or prospectively. No attempt is made to present a detailed
explanation of all U.S. federal income tax concerns affecting the fund or its
shareholders, and the discussion set forth herein does not constitute tax
advice. Investors are urged to consult their own tax advisers to determine the
specific tax consequences to them of investing in the fund, including the
applicable federal, state, local and foreign tax consequences to them and the
effect of possible changes in tax laws.

The fund intends to elect to be treated and to qualify each year as a "regulated
investment company" under Subchapter M of the Code so that it generally will not
pay U.S. federal income tax on income and capital gains distributed to
shareholders. In order to qualify as a regulated investment company under
Subchapter M of the Code, the fund must, (i) among other things, derive at least
90% of its gross income for each taxable year from dividends, interest, payments
with respect to securities loans, gains from the sale or other disposition of
stock, securities or foreign currencies or other income (including gains from
options, futures and forward contracts) derived with respect to its business of
investing in such stock, securities or currencies and net income derived from an
interest in a qualified publicly traded partnership (as defined in Section
851(h) of the Code) (the "90% income test") and (ii) diversify its holdings so
that, at the end of each quarter of each taxable year: (a) at least 50% of the
value of the fund's total assets is represented by (1) cash and cash items, U.S.
government securities, securities of other regulated investment companies, and
(2) other securities, with such other securities limited, in respect to any one
issuer, to an amount not greater than 5% of the value of the fund's total assets
and to not more than 10% of the outstanding voting securities of such issuer and
(b) not more than 25% of the value of the fund's total assets is invested in (1)
the securities (other than U.S. government securities and securities of other
regulated investment companies) of any one issuer, (2) the securities (other
than securities of other regulated investment companies) of two or more issuers
that the fund controls and that are engaged in the same, similar, or related
trades or businesses, or (3) the securities of one or more qualified publicly
traded partnerships.

If the fund qualifies as a regulated investment company and, for each taxable
year, it distributes to its shareholders an amount equal to or exceeding the sum
of (i) 90% of its "investment company taxable income" as that term is defined in
the Code (which includes, among other things, dividends, taxable interest, and
the excess of any net short-term capital gains over net long-term capital
losses, as reduced by


                                       54



certain deductible expenses) and (ii) 90% of the excess of its gross tax-exempt
interest, if any, over certain disallowed deductions, the fund generally will
not be subject to U.S. federal income tax on any income of the fund, including
"net capital gain" (the excess of net long-term capital gain over net short-term
capital loss), distributed to shareholders. However, if the fund has met such
distribution requirements but chooses to retain some portion of its investment
company taxable income or net capital gain, it generally will be subject to U.S.
federal income tax at regular corporate rates on the amount retained. The fund
intends to distribute at least annually all or substantially all of its
investment company taxable income, net tax-exempt interest, and net capital
gain. If for any taxable year, the fund does not qualify as a regulated
investment company, it will be treated as a corporation subject to U.S. federal
income tax and all distributions out of earnings and profits would be taxed to
shareholders as ordinary income. In addition, the fund could be required to
recognize unrealized gains, pay taxes and make distributions (which could be
subject to interest charges) before requalifying as a regulated investment
company.

Under the Code, the fund will be subject to a nondeductible 4% U.S. federal
excise tax on a portion of its undistributed taxable ordinary income and capital
gains if it fails to meet certain distribution requirements with respect to each
calendar year. The fund intends to make distributions in a timely manner and
accordingly does not expect to be subject to the excise tax, but as described
below, there can be no assurance that the fund's distributions will be
sufficient to avoid entirely this tax.

Commencing within approximately 90 days from the date of the filing of the
prospectus, the fund intends to declare a dividend from all or a portion of its
net investment income monthly. The fund intends to distribute any net short- and
long-term capital gains at least annually. Dividends from income and/or capital
gains may also be paid at such other times as may be necessary for the fund to
avoid U.S. federal income or excise tax.

Unless a shareholder is ineligible to participate or elects otherwise, all
distributions from the fund will be automatically reinvested in additional
shares of the fund. For U.S. federal income tax purposes, all dividends
generally are taxed as described below whether a shareholder takes them in cash
or reinvests them in additional shares of the fund. In general, assuming that
the fund has sufficient earnings and profits, dividends from investment company
taxable income are taxable as ordinary income and distributions from net capital
gain, if any, that are designated as capital gain dividends are taxable as
long-term capital gains for U.S. federal income tax purposes without regard to
the length of time the shareholder has held shares of the fund. Since the fund's
income is derived primarily from interest, dividends of the fund from its
investment company taxable income generally will not constitute "qualified
dividend income" for federal income tax purposes and thus will not be eligible
for the favorable federal long-term capital gain tax rates on qualified dividend
income. In addition, the fund's dividends are not expected to qualify for any
dividends-received deduction that might otherwise be available for certain
dividends received by shareholders that are corporations. Capital gain dividends
distributed by the fund to individual shareholders generally will qualify for
the maximum 15% U.S. federal tax rate on long-term capital gains. Under current
law, the maximum 15% U.S. federal tax rate on qualified dividend income and
long-term capital gains will cease to apply to taxable years beginning after
December 31, 2010.

Distributions by the fund in excess of the fund's current and accumulated
earnings and profits will be treated as a return of capital to the extent of
(and in reduction of) the shareholder's tax basis in its shares and any such
amount in excess of that basis will be treated as gain from the sale of shares,
as discussed below. The U.S. federal income tax status of all distributions will
be reported to shareholders annually.

In the case of newly issued shares of the fund (i.e. when there is a market
premium), the amount of the distribution and the basis for federal income tax
purposes of the shares to the shareholders will be equal to the fair market
value of the shares on the distribution date. In the case of shares acquired
through open market purchases (i.e. when there is a market discount), the amount
of the distribution and the basis to


                                       55



shareholders will be equal to the cash they would have received had they elected
to receive cash.

If the fund retains any net capital gain for a taxable year, the fund may
designate the retained amount as undistributed capital gains in a notice to
shareholders who, if subject to U.S. federal income tax on long-term capital
gains, (i) will be required to include in income for U.S. federal income tax
purposes, as long-term capital gain, their proportionate shares of such
undistributed amount, and (ii) will be entitled to credit their proportionate
shares of the tax paid by the fund on the undistributed amount against their
U.S. federal income tax liabilities, if any, and to claim refunds to the extent
the credit exceeds such liabilities.

Although dividends generally will be treated as distributed when paid, any
dividend declared by the fund as of a record date in October, November or
December and paid during the following January will be treated for U.S. federal
income tax purposes as received by shareholders on December 31 of the calendar
year in which it is declared. In addition, certain other distributions made
after the close of a taxable year of the fund may be "spilled back" and treated
as paid by the fund (except for purposes of the 4% excise tax) during such
taxable year. In such case, shareholders generally will be treated as having
received such dividends in the taxable year in which the distributions were
actually made.


The treatment of event-linked bonds for U.S. federal income tax purposes is
uncertain and will depend on the particular features of each such bond. The fund
expects that it will generally treat the event-linked bonds in which it invests
as equity of the issuer for U.S. federal income tax purposes, whether that
treatment is mandated by the terms of the applicable bond indentures or
otherwise, although this determination will necessarily be made on an investment
by investment basis. It is possible that the IRS will provide future guidance
with respect to the treatment of instruments like the event-linked bonds or
challenge the treatment adopted by the fund for one or more of its event-linked
bond investments. A change in the treatment of the fund's event-linked bond
investments that is required as a result of such guidance or an IRS challenge
could affect the timing, character and amount of the fund's income from the
event-linked bonds. This, in turn, could affect whether the fund has satisfied
the distribution requirements necessary to qualify as a regulated investment
company and to avoid a fund-level tax.



An event-linked bond that is treated as equity may be subject to special U.S.
federal income tax rules applicable to equity investments in a passive foreign
investment company (a "PFIC") or a controlled foreign corporation (a "CFC").
Generally, a foreign corporation is treated as a PFIC if it receives at least
75% of its annual gross income from passive sources (such as interest,
dividends, certain rents and royalties, or capital gains) or it holds at least
50% of its assets in investments producing such passive income. In cases in
which the fund treats an event-linked bond as an equity interest in a PFIC, the
fund generally expects to make a "mark to market" election, which would require
the fund to recognize income or (subject to certain limitations) loss annually
based on the difference between the fair market value of the event-linked bond
at the end of the year and the fund's adjusted basis in the event-linked bond.
Because the mark to market election can result in recognition of income without
the concurrent receipt of cash, the fund may have to sell portfolio securities,
thereby possibly resulting in the recognition of additional income or gain, to
satisfy the distribution requirements necessary to qualify as a regulated
investment company and to avoid a fund-level tax. If the fund were not able to
meet such distribution requirements, the fund would run the risk of losing its
qualification as a regulated investment company.



If the fund does not make a mark to market election with respect to an
event-linked bond that is treated as an equity interest in a PFIC, or an
alternative election (if available) that could also require the fund to
recognize income without the concurrent receipt of cash, the fund would be
subject to U.S. federal income tax on payments on the bond to the extent they
constitute "excess distributions" from the PFIC and on gain from the sale or
retirement of the bond, even if all such income or gain is timely distributed by
the fund to its shareholders. Any such income or gain would be allocated pro
rata over the fund's entire holding period for the bond, with the portion of the
income or gain allocated to any prior taxable



                                       56




year being subject to tax at the highest marginal corporate income tax rate in
effect for such prior taxable year. In addition, an interest charge would be
imposed on the fund with respect to taxes deemed to be deferred. The fund would
not be able to pass through to its shareholders any credit or deduction for such
taxes or the interest charge.



If U.S. shareholders (including the fund) collectively are treated as owning
more than 25% of the equity of an issuer of an event-linked bond, the issuer may
be treated as a CFC. In such event, if the fund were considered to own a 10% or
greater equity interest in the CFC as a result of its ownership of the issuer's
event-linked bonds, the fund would generally be required to include in income
annually its pro rata share of certain or all of the CFC's earnings and profits,
whether or not those earnings and profits are distributed as payments on the
event-linked bonds or otherwise. As a result, the fund could be subject to the
distribution requirements discussed above with respect to such income without
the concurrent receipt of cash.


If the fund invests in certain pay-in-kind securities, zero coupon securities,
deferred interest securities or, in general, any other securities with original
issue discount (or with market discount if the fund elects to include market
discount in income currently), the fund generally must accrue income on such
investments for each taxable year, which generally will be prior to the receipt
of the corresponding cash payments. However, the fund must distribute, at least
annually, all or substantially all of its investment company taxable income and
net tax-exempt interest, including such accrued income, to shareholders to
qualify as a regulated investment company under the Code and avoid U.S. federal
income and excise taxes. Therefore, the fund may have to dispose of its
portfolio securities under disadvantageous circumstances to generate cash, or
may have to borrow the cash, to satisfy distribution requirements.

The fund may invest significantly in debt obligations that are in the lowest
rating categories or are unrated, including debt obligations of issuers not
currently paying interest or who are in default. Investments in debt obligations
that are at risk of or in default present special tax issues for the fund. Tax
rules are not entirely clear about issues such as when the fund may cease to
accrue interest, original issue discount or market discount, when and to what
extent deductions may be taken for bad debts or worthless securities, how
payments received on obligations in default should be allocated between
principal and income and whether exchanges of debt obligations in a workout
context are taxable. These and other issues will be addressed by the fund, in
the event it invests in such securities, in order to seek to ensure that it
distributes sufficient income to preserve its status as a regulated investment
company and does not become subject to U.S. federal income or excise tax.

If the fund utilizes leverage through borrowing or issuing preferred shares, a
failure by the fund to meet the asset coverage requirements imposed by the 1940
Act or by any rating organization that has rated such leverage, or additional
restrictions that may be imposed by certain lenders on the payment of dividends
or distributions potentially could limit or suspend the fund's ability to make
distributions on its common shares. Such a limitation or suspension or
limitation could prevent the fund from distributing at least 90% of its
investment company taxable income and net tax-exempt interest as is required
under the Code and therefore might jeopardize the fund's qualification for
taxation as a regulated investment company under the Code and/or might subject
the fund to the 4% excise tax discussed above. Upon any failure to meet such
asset coverage requirements, the fund may, in its sole discretion, purchase or
redeem shares of preferred stock in order to maintain or restore the requisite
asset coverage and avoid the adverse consequences to the fund and its
shareholders of failing to satisfy the distribution requirement. There can be no
assurance, however, that any such action would achieve these objectives. The
fund will endeavor to avoid restrictions on its ability to distribute dividends.

For U.S. federal income tax purposes, the fund is permitted to carry forward an
unused net capital loss for any year to offset its capital gains, if any, for up
to eight years following the year of the loss. To the extent


                                       57



subsequent capital gains are offset by such losses, they would not result in
U.S. federal income tax liability to the fund and are not expected to be
distributed as such to shareholders.

At the time of an investor's purchase of fund shares, a portion of the purchase
price may be attributable to realized or unrealized appreciation in the fund's
portfolio or undistributed taxable income of the fund. Consequently, subsequent
distributions by the fund with respect to these shares from such appreciation or
income may be taxable to such investor even if the trading value of the
investor's shares is, as a result of the distributions, reduced below the
investor's cost for such shares and the distributions economically represent a
return of a portion of the investment.

Foreign exchange gains and losses realized by the fund in connection with
certain transactions involving foreign currency-denominated debt securities,
certain options and futures contracts relating to foreign currency, foreign
currency forward contracts, foreign currencies, or payables or receivables
denominated in a foreign currency are subject to Section 988 of the Code, which
generally causes such gains and losses to be treated as ordinary income and
losses and may affect the amount, timing and character of distributions to
shareholders. Under Treasury regulations that may be promulgated in the future,
any gains from such transactions that are not directly related to the fund's
principal business of investing in stock or securities (or its options contracts
or futures contracts with respect to stock or securities) may have to be limited
in order to enable the fund to satisfy the 90% income test. If the net foreign
exchange loss for a year were to exceed the fund's investment company taxable
income (computed without regard to such loss), the resulting ordinary loss for
such year would not be deductible by the fund or its shareholders in future
years.

Sales and other dispositions of fund shares are taxable events for shareholders
that are subject to tax. Shareholders should consult their own tax advisers with
reference to their individual circumstances to determine whether any particular
transaction in fund shares is properly treated as a sale for tax purposes, as
the following discussion assumes, and the tax treatment of any gains or losses
recognized in such transactions. In general, if fund shares are sold, the
shareholder will recognize gain or loss equal to the difference between the
amount realized on the sale and the shareholder's adjusted tax basis in the
shares sold. Such gain or loss will be treated as long-term capital gain or loss
if the shares sold were held for more than one year and otherwise generally will
be treated as short-term capital gain or loss. Any loss realized by a
shareholder upon the sale or other disposition of shares with a tax holding
period of six months or less will be treated as a long-term capital loss to the
extent of any amounts treated as distributions of long-term capital gains with
respect to such shares. Losses on sales or other dispositions of shares may be
disallowed under "wash sale" rules in the event substantially identical shares
of the fund are purchased (including those made pursuant to reinvestment of
dividends and/or capital gains distributions) within a period of 61 days
beginning 30 days before and ending 30 days after a redemption or other
disposition of shares. In such a case, the disallowed portion of any loss
generally would be included in the U.S. federal tax basis of the shares acquired
in the other investments. The ability to otherwise deduct capital losses may be
subject to other limitations under the Code.

Under Treasury regulations, if a shareholder recognizes a loss with respect to
shares of $2 million or more for an individual shareholder, or $10 million or
more for a corporate shareholder, in any single taxable year (or a greater
amount over a combination of years), the shareholder must file with the IRS a
disclosure statement on Form 8886. Shareholders who own portfolio securities
directly are in many cases excepted from this reporting requirement but, under
current guidance, shareholders of regulated investment companies are not
excepted. A shareholder who fails to make the required disclosure to the IRS may
be subject to substantial penalties. The fact that a loss is reportable under
these regulations does not affect the legal determination of whether or not the
taxpayer's treatment of the loss is proper. Shareholders should consult with
their tax advisers to determine the applicability of these regulations in light
of their individual circumstances.


                                       58



Options written or purchased and futures contracts entered into by the fund on
certain securities, indices and foreign currencies, as well as certain forward
foreign currency contracts, may cause the fund to recognize gains or losses from
marking-to-market even though such options may not have lapsed, been closed out,
or exercised, or such futures and forward contracts may not have been performed
or closed out. The tax rules applicable to these contracts may affect the
characterization of some capital gains and losses realized by the fund as
long-term or short-term. Certain options, futures and forward contracts relating
to foreign currencies may be subject to Section 988, as described above, and
accordingly may produce ordinary income or loss. Additionally, the fund may be
required to recognize gain if an option, futures contract, short sale or other
transaction that is not subject to the mark-to-market rules is treated as a
"constructive sale" of an "appreciated financial position" held by the fund
under Section 1259 of the Code. Any net mark-to-market gains and/or gains from
constructive sales may also have to be distributed to satisfy the distribution
requirements referred to above even though the fund may receive no corresponding
cash amounts, possibly requiring the disposition of portfolio securities or
borrowing to obtain the necessary cash. Losses on certain options, futures or
forward contracts and/or offsetting positions (portfolio securities or other
positions with respect to which the fund's risk of loss is substantially
diminished by one or more options, futures or forward contracts) may also be
deferred under the tax straddle rules of the Code, which may also affect the
characterization of capital gains or losses from straddle positions and certain
successor positions as long-term or short-term. Certain tax elections may be
available that would enable the fund to ameliorate some adverse effects of the
tax rules described in this paragraph. The tax rules applicable to options,
futures, forward contracts and straddles may affect the amount, timing and
character of the fund's income and gains or losses and hence of its
distributions to shareholders.

The federal income tax treatment of the fund's investment in transactions
involving swaps, caps, floors, and collars and structured securities is
uncertain and may be subject to recharacterization by the IRS. To the extent the
tax treatment of such securities or transactions differs from the tax treatment
expected by the fund, the timing or character of income recognized by the fund
could be affected, requiring the fund to purchase or sell securities, or
otherwise change its portfolio, in order to comply with the tax rules applicable
to regulated investment companies under the Code.

The IRS has taken the position that if a regulated investment company has two
classes or more of shares, it must designate distributions made to each class in
any year as consisting of no more than such class's proportionate share of
particular types of income, net capital gain, and ordinary income. A class's
proportionate share of a particular type of income is determined according to
the percentage of total dividends paid by the regulated investment company to
such class. Consequently, if both common shares and preferred shares are
outstanding, the fund intends to designate distributions made to the classes of
particular types of income in accordance with the classes' proportionate shares
of such income. Thus, the fund will designate dividends constituting capital
gain dividends and other taxable dividends in a manner that allocates such
income between the holders of common shares and preferred shares in proportion
to the total dividends paid to each class during the taxable year, or otherwise
as required by applicable law.

The fund may be subject to withholding and other taxes imposed by foreign
countries, including taxes on interest, dividends and capital gains with respect
to its investments in those countries, which would, if imposed, reduce the yield
on or return from those investments. Tax conventions between certain countries
and the U.S. may reduce or eliminate such taxes in some cases. The fund does not
expect to satisfy the requirements for passing through to its shareholders their
pro rata shares of qualified foreign taxes paid by the fund, with the general
result that shareholders would not be entitled to any deduction or credit for
such taxes on their own tax returns.

Federal law requires that the fund withhold (as "backup withholding") 28% of
reportable payments, including dividends, capital gain distributions and the
proceeds of redemptions and exchanges or


                                       59



repurchases of fund shares, paid to shareholders who have not complied with IRS
regulations. In order to avoid this withholding requirement, shareholders must
certify on their Account Applications, or on separate IRS Forms W-9, that the
Social Security Number or other Taxpayer Identification Number they provide is
their correct number and that they are not currently subject to backup
withholding, or that they are exempt from backup withholding. The fund may
nevertheless be required to withhold if it receives notice from the IRS or a
broker that the number provided is incorrect or backup withholding is applicable
as a result of previous underreporting of interest or dividend income.

The description of certain U.S. federal tax provisions above relates only to
U.S. federal income tax consequences for shareholders who are U.S. persons,
i.e., U.S. citizens or residents or U.S. corporations, partnerships, trusts or
estates, and who are subject to U.S. federal income tax. Investors other than
U.S. persons may be subject to different U.S. tax treatment, including a
non-resident alien U.S. withholding tax at the rate of 30% or at a lower treaty
rate on amounts treated as ordinary dividends from the fund (other than certain
dividends derived from short-term capital gains and qualified interest income of
the fund for taxable years of the fund commencing after December 31, 2004 and
prior to January 1, 2008, provided that the fund chooses to make a specific
designation relating to such dividends) and, unless an effective IRS Form W-8BEN
or other authorized withholding certificate is on file, to backup withholding at
the rate of 28% on certain other payments from the fund. Shareholders should
consult their own tax advisers on these matters and on state, local, foreign and
other applicable tax laws.

                                      NOTES


1.   ORGANIZATION



Pioneer Diversified High Income Trust (the "Trust") is a diversified, closed-end
management investment company organized under the Investment Company Act of 1940
on January 30, 2007, which has had no operations other than the sale and
issuance of 4,188 shares at an aggregate purchase price of $100,000 to Pioneer
Investment Management, Inc. ("Pioneer" or the "Adviser"). The Adviser has agreed
to reimburse all of the Trust's organizational expenses and the amount by which
the aggregate of all offering costs (other than the sales load) exceeds $0.05
per common share. "Receivable from Investment Adviser" and "Reimbursement from
Investment Adviser" reflect the anticipated reimbursement by the Adviser of the
Trust's organizational expenses. Offering costs, estimated to be approximately
$1,000,000, up to $0.05 per common share, will be charged to the Trust's
paid-in-capital at the time shares of beneficial interest are sold.



2.   ACCOUNTING POLICIES



The preparation of the financial statements in accordance with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of income and expenses
during the reporting period. Actual results could differ from these estimates.



3.   AGREEMENTS



The Trust has entered into an advisory agreement with the Adviser, which, upon
commencement of investment operations, provides for payment of a monthly fee
computed at the annual rate of 0.85% of the Trust's average daily Managed
Assets. "Managed Assets" means the total assets of the Trust (including any
assets attributable to leverage) minus accrued liabilities (other than
liabilities representing leverage). For purposes of calculating "Managed
Assets," the liquidation preference of any preferred shares outstanding is not
considered a liability. The Adviser has agreed for the first three years of the
Trust's investment operations to limit the Trust's total annual expenses
(excluding offering costs for common and preferred shares, interest expense, the
cost of defending or prosecuting any claim or litigation to which the Trust is a
party (together with any amount in judgment or settlement), indemnification
expenses or taxes incurred due to the failure of the Trust to qualify as a
regulated investment company under the Code or any other nonrecurring or
non-operating expense) to 0.90% of the Trust's average daily managed assets in
year 1, 0.95% of the Trust's average daily managed assets in year 2, and 1.00%
of the Trust's average daily managed assets in year 3. This is a contractual
limit and may not be terminated by the Adviser for three years. There can be no
assurance that it will be continued after that time.



Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly
owned indirect subsidiary of UniCredito Italiano S.p.A., and an affiliate of the
Adviser, has contracted with the Trust to provide transfer agent and shareholder
services to the Trust. PIMSS has retained American Stock Transfer & Trust
Company ("AST") to provide sub-transfer agent, registrar, shareholder servicing
agent and dividend dispersing agent services for the Trust. PIMSS, and not the
Trust, is responsible for paying the costs of AST's services.



The Trust has entered into an administration agreement with the Adviser,
pursuant to which the Adviser will provide certain administrative and accounting
services to the Trust. The Adviser has appointed Princeton Administrators, LLC
("Princeton") as the sub-administrator to the Trust to perform certain of the
Adviser's administration and accounts obligations to the Trust. Under the
administration agreement, the Trust will pay the Adviser a monthly fee equal to
0.07% of the Trust's average daily Managed Assets up to $500 million and 0.03%
for average daily Managed Assets in excess of $500 million. The Adviser, and not
the Trust, is responsible for paying the fees of



                                       63




Princeton, which is affiliated with Merrill, Lynch & Co., one of the potential
underwriters of the Trust's offering of common shares. Pursuant to a separate
agreement, the Trust may compensate the Adviser for providing certain legal and
accounting services.



4.   FEDERAL INCOME TAXES



The Trust intends to qualify as a "regulated investment company" and to comply
with the applicable provisions of the Internal Revenue Code, such that it will
not be subject to Federal income tax on taxable income (including realized
capital gains) that is distributed to shareholders.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the Board of Trustees and Shareowners of
Pioneer Diversified High Income Trust:



We have audited the accompanying statement of assets and liabilities of Pioneer
Diversified High Income Trust (the "Trust"), as of April 12, 2007 (date of
capitalization), and the related statement of operations for the one-day period
then ended. These financial statements are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.



We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. We were not engaged to perform an
audit of the Trust's internal control over financial reporting. Our audit
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Trust's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.



In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Pioneer Diversified High Income
Trust at April 12, 2007 (date of capitalization), and the results of its
operations for the one-day period then ended, in conformity with U.S. generally
accepted accounting principles.

APPENDIX A - DESCRIPTION OF SHORT-TERM DEBT, CORPORATE BOND AND PREFERRED STOCK
RATINGS(1)

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") PRIME RATING SYSTEM

Moody's short-term ratings are opinions of the ability of issuers to honor
senior financial obligations and contracts. Such obligations generally have an
original maturity not exceeding one year, unless explicitly noted.

Moody's employs the following designations, all judged to be investment grade,
to indicate the relative repayment ability of rated issuers:

Prime-1: Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:

Leading market positions in well-established industries.

High rates of return on funds employed.

Conservative capitalization structure with moderate reliance on debt and ample
asset protection.

Broad margins in earnings coverage of fixed financial charges and high internal
cash generation.

Well-established access to a range of financial markets and assured sources of
alternate liquidity.

Prime-2: Issuers (or supporting institutions) rated Prime-2 have a strong
ability to repay senior short-term debt obligations. This will normally be
evidenced by many of the characteristics cited above, but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation than is the case for Prime-2 securities. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.

Prime-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable
ability for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt-protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

Not Prime: Issuers rated Not Prime do not fall within any of the Prime rating
categories.

In addition, in certain countries the prime rating may be modified by the
issuer's or guarantor's senior unsecured long-term debt rating.

MOODY'S DEBT RATINGS

Aaa: Bonds and preferred stock which are rated Aaa are judged to be of the best
quality. They carry the smallest degree of investment risk and are generally
referred to as "gilt edged." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various


----------
(1)  The ratings indicated herein are believed to be the most recent ratings
     available at the date of this statement of additional information for the
     securities listed. Ratings are generally given to securities at the time of
     issuance. While the rating agencies may from time to time revise such
     ratings, they undertake no obligation to do so, and the ratings indicated
     do not necessarily represent ratings which will be given to these
     securities on the date of the fund's fiscal year-end.



                                       66



protective elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

Aa: Bonds and preferred stock which are rated Aa are judged to be of high
quality by all standards. Together with the Aaa group they comprise what are
generally known as high-grade bonds. They are rated lower than the best bonds
because margins of protection may not be as large as in Aaa securities or
fluctuation of protective elements may be of greater amplitude or there may be
other elements present which make the long-term risk appear somewhat larger than
the Aaa securities.

A: Bonds and preferred stock which are rated A possess many favorable investment
attributes and are to be considered as upper-medium-grade obligations. Factors
giving security to principal and interest are considered adequate, but elements
may be present which suggest a susceptibility to impairment some time in the
future.

Baa: Bonds and preferred stock which are rated Baa are considered as
medium-grade obligations (i.e., they are neither highly protected nor poorly
secured). Interest payments and principal security appear adequate for the
present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time. Such bonds lack
outstanding investment characteristics and in fact have speculative
characteristics as well.

Ba: Bonds and preferred stock which are rated Ba are judged to have speculative
elements; their future cannot be considered as well-assured. Often the
protection of interest and principal payments may be very moderate, and thereby
not well safeguarded during both good and bad times over the future. Uncertainty
of position characterizes bonds in this class.

B: Bonds and preferred stock which are rated B generally lack characteristics of
the desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

Caa: Bonds and preferred stock which are rated Caa are of poor standing. Such
issues may be in default or there may be present elements of danger with respect
to principal or interest.

Ca: Bonds and preferred stock which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings.

C: Bonds and preferred stock which are rated C are the lowest rated class of
bonds, and issues so rated can be regarded as having extremely poor prospects of
ever attaining any real investment standing.

Moody's assigns ratings to individual debt securities issued from medium-term
note (MTN) programs, in addition to indicating ratings to MTN programs
themselves. Notes issued under MTN programs with such indicated ratings are
rated at issuance at the rating applicable to all pari passu notes issued under
the same program, at the program's relevant indicated rating, provided such
notes do not exhibit any of the characteristics listed below. For notes with any
of the following characteristics, the rating of the individual note may differ
from the indicated rating of the program:

1) Notes containing features which link the cash flow and/or market value to the
credit performance of any third party or parties.

2) Notes allowing for negative coupons, or negative principal.

3) Notes containing any provision which could obligate the investor to make any
additional payments.

Market participants must determine whether any particular note is rated, and if
so, at what rating level.


                                       67



Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating
classification from Aa through Caa. The modifier 1 indicates that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

A-1: A short-term obligation rated A-1 is rated in the highest category by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

B: A short-term obligation rated B is regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in payment default. The D rating category
is used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

STANDARD & POOR'S LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based, in varying degrees, on the following
considerations:

     -    Likelihood of payment-capacity and willingness of the obligor to meet
          its financial commitment on an obligation in accordance with the terms
          of the obligation;

     -    Nature of and provisions of the obligation;

     -    Protection afforded by, and relative position of, the obligation in
          the event of bankruptcy, reorganization, or other arrangement under
          the laws of bankruptcy and other laws affecting creditors' rights.

The issue rating definitions are expressed in terms of default risk. As such,
they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding


                                       68



company obligations.) Accordingly, in the case of junior debt, the rating may
not conform exactly with the category definition.

AAA: An obligation rated AAA has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

AA: An obligation rated AA differs from the highest rated obligations only in
small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.

A: An obligation rated A is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in higher
rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

Obligations rated BB, B, CCC, CC, and C are regarded as having significant
speculative characteristics. BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major
exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated
BB, but the obligor currently has the capacity to meet its financial commitment
on the obligation. Adverse business, financial, or economic conditions will
likely impair the obligor's capacity or willingness to meet its financial
commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment, and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment.

C: A subordinated debt or preferred stock obligation rated C is currently highly
vulnerable to nonpayment. The C rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action taken, but payments on this
obligation are being continued. A C also will be assigned to a preferred stock
issue in arrears on dividends or sinking fund payments, but that is currently
paying.

D: An obligation rated D is in payment default. The D rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

Plus (+) or minus (-): The ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.


                                       69



r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating.

N.R.: This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.

LOCAL CURRENCY AND FOREIGN CURRENCY RISKS

Country risk considerations are a standard part of Standard & Poor's analysis
for credit ratings on any issuer or issue. Currency of repayment is a key factor
in this analysis. An obligor's capacity to repay foreign currency obligations
may be lower than its capacity to repay obligations in its local currency due to
the sovereign government's own relatively lower capacity to repay external
versus domestic debt. These sovereign risk considerations are incorporated in
the debt ratings assigned to specific issues. Foreign currency issuer ratings
are also distinguished from local currency issuer ratings to identify those
instances where sovereign risks make them different for the same issuer.

The ratings indicated herein are believed to be the most recent ratings
available at the date of this statement of additional information for the
securities listed. Ratings are generally given to securities at the time of
issuance. While the rating agencies may from time to time revise such ratings,
they undertake no obligation to do so, and the ratings indicated do not
necessarily represent ratings which will be given to these securities on the
date of the fund's fiscal year-end.

APPENDIX B - PROXY VOTING POLICIES

                     PROXY VOTING POLICIES AND PROCEDURES OF
                       PIONEER INVESTMENT MANAGEMENT, INC.

                            VERSION DATED JULY, 2004

                                    OVERVIEW

Pioneer Investment Management, Inc. ("Pioneer") is a fiduciary that owes each of
its client's duties of care and loyalty with respect to all services undertaken
on the client's behalf, including proxy voting. When Pioneer has been delegated
proxy-voting authority for a client, the duty of care requires Pioneer to
monitor corporate events and to vote the proxies. To satisfy its duty of
loyalty, Pioneer must place its client's interests ahead of its own and must
cast proxy votes in a manner consistent with the best interest of its clients.
Pioneer will vote all proxies presented in a timely manner.

The Proxy Voting Policies and Procedures are designed to complement Pioneer's
investment policies and procedures regarding its general responsibility to
monitor the performance and/or corporate events of companies that are issuers of
securities held in accounts managed by Pioneer. Pioneer's Proxy Voting Policies
summarize Pioneer's position on a number of issues solicited by companies held
by Pioneer's clients. The policies are guidelines that provide a general
indication on how Pioneer would vote but do not include all potential voting
scenarios.

Pioneer's Proxy Voting Procedures detail monitoring of voting, exception votes,
and review of conflicts of interest and ensure that case-by-case votes are
handled within the context of the overall guidelines (i.e. best interest of
client). The overriding goal is that all proxies for US and non-US companies
that are received promptly will be voted in accordance with Pioneer's policies
or specific client instructions. All shares in a company held by Pioneer-managed
accounts will be voted alike, unless a client has given us specific voting
instructions on an issue or has not delegated authority to us or the Proxy
Voting Oversight Group determines that the circumstances justify a different
approach.

Pioneer does not delegate the authority to vote proxies relating to its clients
to any of its affiliates, which include other subsidiaries of UniCredito.

ANY QUESTIONS ABOUT THESE POLICIES AND PROCEDURES SHOULD BE DIRECTED TO THE
PROXY COORDINATOR.


                                       71


                             PROXY VOTING PROCEDURES

PROXY VOTING SERVICE

Pioneer has engaged an independent proxy voting service to assist in the voting
of proxies. The proxy voting service works with custodians to ensure that all
proxy materials are received by the custodians and are processed in a timely
fashion. To the extent applicable, the proxy voting service votes all proxies in
accordance with the proxy voting policies established by Pioneer. The proxy
voting service will refer proxy questions to the Proxy Coordinator (described
below) for instructions under circumstances where: (1) the application of the
proxy voting guidelines is unclear; (2) a particular proxy question is not
covered by the guidelines; or (3) the guidelines call for specific instructions
on a case-by-case basis. The proxy voting service is also requested to call to
the Proxy Coordinator's attention specific proxy questions that, while governed
by a guideline, appear to involve unusual or controversial issues. Pioneer
reserves the right to attend a meeting in person and may do so when it
determines that the company or the matters to be voted on at the meeting are
strategically important to its clients.

PROXY COORDINATOR

Pioneer's Director of Investment Operations (the "Proxy Coordinator")
coordinates the voting, procedures and reporting of proxies on behalf of
Pioneer's clients. The Proxy Coordinator will deal directly with the proxy
voting service and, in the case of proxy questions referred by the proxy voting
service, will solicit voting recommendations and instructions from the Director
of Portfolio Management US or, to the extent applicable, investment
sub-advisers. The Proxy Coordinator is responsible for ensuring that these
questions and referrals are responded to in a timely fashion and for
transmitting appropriate voting instructions to the proxy voting service. The
Proxy Coordinator is responsible for verifying with the Compliance Department
whether Pioneer's voting power is subject to any limitations or guidelines
issued by the client (or in the case of an employee benefit plan, the plan's
trustee or other fiduciaries).

REFERRAL ITEMS

From time to time, the proxy voting service will refer proxy questions to the
Proxy Coordinator that are described by Pioneer's policy as to be voted on a
case-by-case basis, that are not covered by Pioneer's guidelines or where
Pioneer's guidelines may be unclear with respect to the matter to be voted on.
Under such certain circumstances, the Proxy Coordinator will seek a written
voting recommendation from the Director of Portfolio Management US. Any such
recommendation will include: (i) the manner in which the proxies should be
voted; (ii) the rationale underlying any such decision; and (iii) the disclosure
of any contacts or communications made between Pioneer and any outside parties
concerning the proxy proposal prior to the time that the voting instructions are
provided. In addition, the Proxy Coordinator will ask the Compliance Department
to review the question for any actual or apparent conflicts of interest as
described below under "Conflicts of Interest." The Compliance Department will
provide a "Conflicts of Interest Report," applying the criteria set forth below
under "Conflicts of Interest," to the Proxy Coordinator summarizing the results
of its review. In the absence of a conflict of interest, the Proxy Coordinator
will vote in accordance with the recommendation of the Director of Portfolio
Management US.

If the matter presents a conflict of interest for Pioneer, then the Proxy
Coordinator will refer the matter to the Proxy Voting Oversight Group for a
decision. In general, when a conflict of interest is present, Pioneer will vote
according to the recommendation of the Director of Portfolio Management US where
such recommendation would go against Pioneer's interest or where the conflict is
deemed to be immaterial. Pioneer will vote according to the recommendation of
its proxy voting service when the conflict is deemed to be material and the
Pioneer's internal vote recommendation would favor Pioneer's


                                       72



interest, unless a client specifically requests Pioneer to do otherwise. When
making the final determination as to how to vote a proxy, the Proxy Voting
Oversight Group will review the report from the Director of Portfolio Management
US and the Conflicts of Interest Report issued by the Compliance Department.

CONFLICTS OF INTEREST

A conflict of interest occurs when Pioneer's interests interfere, or appear to
interfere with the interests of Pioneer's clients. Occasionally, Pioneer may
have a conflict that can affect how its votes proxies. The conflict may be
actual or perceived and may exist when the matter to be voted on concerns:

     -    An affiliate of Pioneer, such as another company belonging to the
          UniCredito Italiano S.p.A. banking group (a "UniCredito Affiliate");

     -    An issuer of a security for which Pioneer acts as a sponsor, advisor,
          manager, custodian, distributor, underwriter, broker, or other similar
          capacity (including those securities specifically declared by PGAM to
          present a conflict of interest for Pioneer);

     -    An issuer of a security for which UniCredito has informed Pioneer that
          a UniCredito Affiliate acts as a sponsor, advisor, manager, custodian,
          distributor, underwriter, broker, or other similar capacity; or

     -    A person with whom Pioneer (or any of its affiliates) has an existing,
          material contract or business relationship that was not entered into
          in the ordinary course of Pioneer's business.

     -    Pioneer will abstain from voting with respect to companies directly or
          indirectly owned by UniCredito Italiano Group, unless otherwise
          directed by a client. In addition, Pioneer will inform PGAM Global
          Compliance and the PGAM Independent Directors before exercising such
          rights.

Any associate involved in the proxy voting process with knowledge of any
apparent or actual conflict of interest must disclose such conflict to the Proxy
Coordinator and the Compliance Department. The Compliance Department will review
each item referred to Pioneer to determine whether an actual or potential
conflict of interest with Pioneer exists in connection with the proposal(s) to
be voted upon. The review will be conducted by comparing the apparent parties
affected by the proxy proposal being voted upon against the Compliance
Department's internal list of interested persons and, for any matches found,
evaluating the anticipated magnitude and possible probability of any conflict of
interest being present. For each referral item, the determination regarding the
presence or absence of any actual or potential conflict of interest will be
documented in a Conflicts of Interest Report to the Proxy Coordinator.

SECURITIES LENDING

In conjunction with industry standards Proxies are not available to be voted
when the shares are out on loan through either Pioneer's lending program or a
client's managed security lending program. However, Pioneer will reserve the
right to recall lent securities so that they may be voted according to the
Pioneer's instructions. If a portfolio manager would like to vote a block of
previously lent shares, the Proxy Coordinator will work with the portfolio
manager and Investment Operations to recall the security, to the extent
possible, to facilitate the vote on the entire block of shares.

SHARE-BLOCKING

"Share-blocking" is a market practice whereby shares are sent to a custodian
(which may be different than the account custodian) for record keeping and
voting at the general meeting. The shares are unavailable for sale or delivery
until the end of the blocking period (typically the day after general meeting
date).


                                       73



Pioneer will vote in those countries with "share-blocking." In the event a
manager would like to sell a security with "share-blocking", the Proxy
Coordinator will work with the Portfolio Manager and Investment Operations
Department to recall the shares (as allowable within the market time-frame and
practices) and/or communicate with executing brokerage firm. A list of countries
with "share-blocking" is available from the Investment Operations Department
upon request.

RECORD KEEPING

The Proxy Coordinator shall ensure that Pioneer's proxy voting service:

     -    Retains a copy of the proxy statement received (unless the proxy
          statement is available from the SEC's Electronic Data Gathering,
          Analysis, and Retrieval (EDGAR) system);

     -    Retains a record of the vote cast;

     -    Prepares Form N-PX for filing on behalf of each client that is a
          registered investment company; and

     -    Is able to promptly provide Pioneer with a copy of the voting record
          upon its request.

The Proxy Coordinator shall ensure that for those votes that may require
additional documentation (i.e. conflicts of interest, exception votes and
case-by-case votes) the following records are maintained:

     -    A record memorializing the basis for each referral vote cast;

     -    A copy of any document created by Pioneer that was material in making
          the decision on how to vote the subject proxy; and

     -    A copy of any conflict notice, conflict consent or any other written
          communication (including emails or other electronic communications) to
          or from the client (or in the case of an employee benefit plan, the
          plan's trustee or other fiduciaries) regarding the subject proxy vote
          cast by, or the vote recommendation of, Pioneer.

Pioneer shall maintain the above records in the client's file for a period not
less than ten (10) years.

DISCLOSURE

Pioneer shall take reasonable measures to inform its clients of the process or
procedures clients must follow to obtain information regarding how Pioneer voted
with respect to assets held in their accounts. In addition, Pioneer shall
describe to clients its proxy voting policies and procedures and will furnish a
copy of its proxy voting policies and procedures upon request. This information
may be provided to clients through Pioneer's Form ADV (Part II) disclosure, by
separate notice to the client, or through Pioneer's website.

PROXY VOTING OVERSIGHT GROUP

The members of the Proxy Voting Oversight Group are Pioneer's: Director of
Portfolio Management US, Head of Investment Operations, and Director of
Compliance. Other members of Pioneer will be invited to attend meetings and
otherwise participate as necessary. The Head of Investment Operations will chair
the Proxy Voting Oversight Group.

The Proxy Voting Oversight Group is responsible for developing, evaluating, and
changing (when necessary) Pioneer's Proxy Voting Policies and Procedures. The
group meets at least annually to evaluate


                                       74



and review these policies and procedures and the services of its third-party
proxy voting service. In addition, the Proxy Voting Oversight Group will meet as
necessary to vote on referral items and address other business as necessary.

AMENDMENTS

Pioneer may not amend its Proxy Voting Policies And Procedures without the prior
approval of the Proxy Voting Oversight Group and its corporate parent, Pioneer
Global Asset Management S.p.A

                              PROXY VOTING POLICIES

Pioneer's sole concern in voting proxies is the economic effect of the proposal
on the value of portfolio holdings, considering both the short- and long-term
impact. In many instances, Pioneer believes that supporting the company's
strategy and voting "for" management's proposals builds portfolio value. In
other cases, however, proposals set forth by management may have a negative
effect on that value, while some shareholder proposals may hold the best
prospects for enhancing it. Pioneer monitors developments in the proxy-voting
arena and will revise this policy as needed.

All proxies that are received promptly will be voted in accordance with the
specific policies listed below. All shares in a company held by Pioneer-managed
accounts will be voted alike, unless a client has given us specific voting
instructions on an issue or has not delegated authority to us. Proxy voting
issues will be reviewed by Pioneer's Proxy Voting Oversight Group, which
consists of the Director of Portfolio Management US, the Director of Investment
Operations (the Proxy Coordinator), and the Director of Compliance.

Pioneer has established Proxy Voting Procedures for identifying and reviewing
conflicts of interest that may arise in the voting of proxies.

Clients may request, at any time, a report on proxy votes for securities held in
their portfolios and Pioneer is happy to discuss our proxy votes with company
management. Pioneer retains a proxy voting service to provide research on proxy
issues and to process proxy votes.

ADMINISTRATIVE

While administrative items appear infrequently in U.S. issuer proxies, they are
quite common in non-U.S. proxies.

We will generally support these and similar management proposals:

     -    Corporate name change.

     -    A change of corporate headquarters.

     -    Stock exchange listing.

     -    Establishment of time and place of annual meeting.

     -    Adjournment or postponement of annual meeting.

     -    Acceptance/approval of financial statements.


                                       75



     -    Approval of dividend payments, dividend reinvestment plans and other
          dividend-related proposals.

     -    Approval of minutes and other formalities.

     -    Authorization of the transferring of reserves and allocation of
          income.

     -    Amendments to authorized signatories.

     -    Approval of accounting method changes or change in fiscal year-end.

     -    Acceptance of labor agreements.

     -    Appointment of internal auditors.

Pioneer will vote on a case-by-case basis on other routine business; however,
Pioneer will oppose any routine business proposal if insufficient information is
presented in advance to allow Pioneer to judge the merit of the proposal.
Pioneer has also instructed its proxy voting service to inform Pioneer of its
analysis of any administrative items inconsistent, in its view, with supporting
the value of Pioneer portfolio holdings so that Pioneer may consider and vote on
those items on a case-by-case basis.

AUDITORS

We normally vote for proposals to:

     -    Ratify the auditors. We will consider a vote against if we are
          concerned about the auditors' independence or their past work for the
          company. Specifically, we will oppose the ratification of auditors and
          withhold votes from audit committee members if non-audit fees paid by
          the company to the auditing firm exceed the sum of audit fees plus
          audit-related fees plus permissible tax fees according to the
          disclosure categories proposed by the Securities and Exchange
          Commission.

     -    Restore shareholder rights to ratify the auditors.

We will normally oppose proposals that require companies to:

     -    Seek bids from other auditors.

     -    Rotate auditing firms, except where the rotation is statutorily
          required or where rotation would demonstrably strengthen financial
          disclosure.

     -    Indemnify auditors.

     -    Prohibit auditors from engaging in non-audit services for the company.

BOARD OF DIRECTORS

On issues related to the board of directors, Pioneer normally supports
management. We will, however, consider a vote against management in instances
where corporate performance has been very poor or where the board appears to
lack independence.

GENERAL BOARD ISSUES


                                       76



Pioneer will vote for:

     -    Audit, compensation and nominating committees composed of independent
          directors exclusively.

     -    Indemnification for directors for actions taken in good faith in
          accordance with the business judgment rule. We will vote against
          proposals for broader indemnification.

     -    Changes in board size that appear to have a legitimate business
          purpose and are not primarily for anti-takeover reasons.

     -    Election of an honorary director.

We will vote against:

     -    Minimum stock ownership by directors.

     -    Term limits for directors. Companies benefit from experienced
          directors, and shareholder control is better achieved through annual
          votes.

     -    Requirements for union or special interest representation on the
          board.

     -    Requirements to provide two candidates for each board seat.

We will vote on a case-by case basis on these issues:

     -    Separate chairman and CEO positions. We will consider voting with
          shareholders on these issues in cases of poor corporate performance.

ELECTIONS OF DIRECTORS

In uncontested elections of directors we will vote against:

     -    Individual directors with absenteeism above 25% without valid reason.
          We support proposals that require disclosure of director attendance.

     -    Insider directors and affiliated outsiders who sit on the audit,
          compensation, stock option or nominating committees. For the purposes
          of our policy, we accept the definition of affiliated directors
          provided by our proxy voting service.

We will also vote against:

     -    Directors who have failed to act on a takeover offer where the
          majority of shareholders have tendered their shares.

     -    Directors who appear to lack independence or are associated with very
          poor corporate performance.

We will vote on a case-by case basis on these issues:

     -    Re-election of directors who have implemented or renewed a dead-hand
          or modified dead-hand poison pill (a "dead-hand poison pill" is a
          shareholder rights plan that may be altered only by incumbent or
          "dead" directors. These plans prevent a potential acquirer from
          disabling a poison pill by obtaining control of the board through a
          proxy vote).


                                       77



     -    Contested election of directors.

     -    Prior to phase-in required by SEC, we would consider supporting
          election of a majority of independent directors in cases of poor
          performance.

     -    Mandatory retirement policies.

     -    Directors who have ignored a shareholder proposal that has been
          approved by shareholders for two consecutive years.


TAKEOVER-RELATED MEASURES

Pioneer is generally opposed to proposals that may discourage takeover attempts.
We believe that the potential for a takeover helps ensure that corporate
performance remains high. Pioneer will vote for:

     -    Cumulative voting.

     -    Increase ability for shareholders to call special meetings.

     -    Increase ability for shareholders to act by written consent.

     -    Restrictions on the ability to make greenmail payments.

     -    Submitting rights plans to shareholder vote.

     -    Rescinding shareholder rights plans ("poison pills").

     -    Opting out of the following state takeover statutes:

     -    Control share acquisition statutes, which deny large holders voting
          rights on holdings over a specified threshold.

     -    Control share cash-out provisions, which require large holders to
          acquire shares from other holders.

     -    Freeze-out provisions, which impose a waiting period on large holders
          before they can attempt to gain control.

     -    Stakeholder laws, which permit directors to consider interests of
          non-shareholder constituencies.

     -    Disgorgement provisions, which require acquirers to disgorge profits
          on purchases made before gaining control.

     -    Fair price provisions.

     -    Authorization of shareholder rights plans.

     -    Labor protection provisions.

     -    Mandatory classified boards.


                                       78



We will vote on a case-by-case basis on the following issues:

     -    Fair price provisions. We will vote against provisions requiring
          supermajority votes to approve takeovers. We will also consider voting
          against proposals that require a supermajority vote to repeal or amend
          the provision. Finally, we will consider the mechanism used to
          determine the fair price; we are generally opposed to complicated
          formulas or requirements to pay a premium.

     -    Opting out of state takeover statutes regarding fair price provisions.
          We will use the criteria used for fair price provisions in general to
          determine our vote on this issue.

     -    Proposals that allow shareholders to nominate directors.

We will vote against:

     -    Classified boards, except in the case of closed-end mutual funds.

     -    Limiting shareholder ability to remove or appoint directors. We will
          support proposals to restore shareholder authority in this area. We
          will review on a case-by-case basis proposals that authorize the board
          to make interim appointments.

     -    Classes of shares with unequal voting rights.

     -    Supermajority vote requirements.

     -    Severance packages ("golden" and "tin" parachutes). We will support
          proposals to put these packages to shareholder vote.

     -    Reimbursement of dissident proxy solicitation expenses. While we
          ordinarily support measures that encourage takeover bids, we believe
          that management should have full control over corporate funds.

     -    Extension of advance notice requirements for shareholder proposals.

     -    Granting board authority normally retained by shareholders (e.g.,
          amend charter, set board size).

     -    Shareholder rights plans ("poison pills"). These plans generally allow
          shareholders to buy additional shares at a below-market price in the
          event of a change in control and may deter some bids.

CAPITAL STRUCTURE

Managements need considerable flexibility in determining the company's financial
structure, and Pioneer normally supports managements' proposals in this area. We
will, however, reject proposals that impose high barriers to potential
takeovers.

Pioneer will vote for:

     -    Changes in par value.

     -    Reverse splits, if accompanied by a reduction in number of shares.

     -    Share repurchase programs, if all shareholders may participate on
          equal terms.


                                       79



     -    Bond issuance.

     -    Increases in "ordinary" preferred stock.

     -    Proposals to have blank-check common stock placements (other than
          shares issued in the normal course of business) submitted for
          shareholder approval.

     -    Cancellation of company treasury shares.

We will vote on a case-by-case basis on the following issues:

     -    Reverse splits not accompanied by a reduction in number of shares,
          considering the risk of delisting.

     -    Increase in authorized common stock. We will make a determination
          considering, among other factors:

     -    Number of shares currently available for issuance;

     -    Size of requested increase (we would normally approve increases of up
          to 100% of current authorization);

     -    Proposed use of the additional shares; and

     -    Potential consequences of a failure to increase the number of shares
          outstanding (e.g., delisting or bankruptcy).

     -    Blank-check preferred. We will normally oppose issuance of a new class
          of blank-check preferred, but may approve an increase in a class
          already outstanding if the company has demonstrated that it uses this
          flexibility appropriately.

     -    Proposals to submit private placements to shareholder vote.

     -    Other financing plans.

We will vote against preemptive rights that we believe limit a company's
financing flexibility.

COMPENSATION

Pioneer supports compensation plans that link pay to shareholder returns and
believes that management has the best understanding of the level of compensation
needed to attract and retain qualified people. At the same time, stock-related
compensation plans have a significant economic impact and a direct effect on the
balance sheet. Therefore, while we do not want to micromanage a company's
compensation programs, we will place limits on the potential dilution these
plans may impose.

Pioneer will vote for:

     -    401(k) benefit plans.

     -    Employee stock ownership plans (ESOPs), as long as shares allocated to
          ESOPs are less than 5% of outstanding shares. Larger blocks of stock
          in ESOPs can serve as a takeover defense. We will support proposals to
          submit ESOPs to shareholder vote.


                                       80



     -    Various issues related to the Omnibus Budget and Reconciliation Act of
          1993 (OBRA), including:

     -    Amendments to performance plans to conform with OBRA;

     -    Caps on annual grants or amendments of administrative features;

     -    Adding performance goals; and

     -    Cash or cash-and-stock bonus plans.

     -    Establish a process to link pay, including stock-option grants, to
          performance, leaving specifics of implementation to the company.

     -    Require that option repricings be submitted to shareholders.

     -    Require the expensing of stock-option awards.

     -    Require reporting of executive retirement benefits (deferred
          compensation, split-dollar life insurance, SERPs, and pension
          benefits).

     -    Employee stock purchase plans where the purchase price is equal to at
          least 85% of the market price, where the offering period is no greater
          than 27 months and where potential dilution (as defined below) is no
          greater than 10%.

We will vote on a case-by-case basis on the following issues:

     -    Executive and director stock-related compensation plans. We will
          consider the following factors when reviewing these plans:

          -    The program must be of a reasonable size. We will approve plans
               where the combined employee and director plans together would
               generate less than 15% dilution. We will reject plans with 15% or
               more potential dilution.

               Dilution = (A + B + C) / (A + B + C + D), where

               A = Shares reserved for plan/amendment,
               B = Shares available under continuing plans,
               C = Shares granted but unexercised and
               D = Shares outstanding.

          -    The plan must not:

               -    Explicitly permit unlimited option repricing authority or
                    that have repriced in the past without shareholder approval.

               -    Be a self-replenishing "evergreen" plan, plans that grant
                    discount options and tax offset payments.

     -    We are generally in favor of proposals that increase participation
          beyond executives.


                                       81



     -    We generally support proposals asking companies to adopt rigorous
          vesting provisions for stock option plans such as those that vest
          incrementally over, at least, a three- or four-year period with a pro
          rata portion of the shares becoming exercisable on an annual basis
          following grant date.

     -    We generally support proposals asking companies to disclose their
          window period policies for stock transactions. Window period policies
          ensure that employees do not exercise options based on insider
          information contemporaneous with quarterly earnings releases and other
          material corporate announcements.

     -    We generally support proposals asking companies to adopt stock holding
          periods for their executives.

     -    All other employee stock purchase plans.

     -    All other compensation-related proposals, including deferred
          compensation plans, employment agreements, loan guarantee programs and
          retirement plans.

     -    All other proposals regarding stock compensation plans, including
          extending the life of a plan, changing vesting restrictions, repricing
          options, lengthening exercise periods or accelerating distribution of
          awards and pyramiding and cashless exercise programs.

We will vote against:

     -    Pensions for non-employee directors. We believe these retirement plans
          reduce director objectivity.

     -    Elimination of stock option plans.

We will vote on a case-by case basis on these issues:

     -    Limits on executive and director pay.

     -    Stock in lieu of cash compensation for directors.

CORPORATE GOVERNANCE

Pioneer will vote for:

     -    Confidential Voting.

     -    Equal access provisions, which allow shareholders to contribute their
          opinion to proxy materials.

     -    Proposals requiring directors to disclose their ownership of shares in
          the company.

We will vote on a case-by-case basis on the following issues:

     -    Change in the state of incorporation. We will support reincorporations
          supported by valid business reasons. We will oppose those that appear
          to be solely for the purpose of strengthening takeover defenses.

     -    Bundled proposals. We will evaluate the overall impact of the
          proposal.


                                       82



     -    Adopting or amending the charter, bylaws or articles of association.

     -    Shareholder appraisal rights, which allow shareholders to demand
          judicial review of an acquisition price.

We will vote against:

     -    Shareholder advisory committees. While management should solicit
          shareholder input, we prefer to leave the method of doing so to
          management's discretion.

     -    Limitations on stock ownership or voting rights.

     -    Reduction in share ownership disclosure guidelines.

MERGERS AND RESTRUCTURINGS

Pioneer will vote on the following and similar issues on a case-by-case basis:

     -    Mergers and acquisitions.

     -    Corporate restructurings, including spin-offs, liquidations, asset
          sales, joint ventures, conversions to holding company and conversions
          to self-managed REIT structure.

     -    Debt restructurings.

     -    Conversion of securities.

     -    Issuance of shares to facilitate a merger.

     -    Private placements, warrants, convertible debentures.

     -    Proposals requiring management to inform shareholders of merger
          opportunities.

We will normally vote against shareholder proposals requiring that the company
be put up for sale.

MUTUAL FUNDS

Many of our portfolios may invest in shares of closed-end mutual funds or
exchange-traded funds. The non-corporate structure of these investments raises
several unique proxy voting issues.

Pioneer will vote for:

     -    Establishment of new classes or series of shares.

     -    Establishment of a master-feeder structure.

Pioneer will vote on a case-by-case on:

     -    Changes in investment policy. We will normally support changes that do
          not affect the investment objective or overall risk level of the fund.
          We will examine more fundamental changes on a case-by-case basis.


                                       83



     -    Approval of new or amended advisory contracts.

     -    Changes from closed-end to open-end format.

     -    Authorization for, or increase in, preferred shares.

     -    Disposition of assets, termination, liquidation, or mergers.

     -    Classified boards of closed-end mutual funds, but will typically
          support such proposals.

SOCIAL ISSUES

Pioneer will abstain on stockholder proposals calling for greater disclosure of
corporate activities with regard to social issues. "Social Issues" may generally
be described as shareholder proposals for a company to:

     -    Conduct studies regarding certain issues of public concern and
          interest;

     -    Study the feasibility of the company taking certain actions with
          regard to such issues; or

     -    Take specific action, including ceasing certain behavior and adopting
          company standards and principles, in relation to issues of public
          concern and interest.

We believe these issues are important and should receive management attention.

Pioneer will vote against proposals calling for substantial changes in the
company's business or activities. We will also normally vote against proposals
with regard to contributions, believing that management should control the
routine disbursement of funds.

Common Shares (no par value)   1




Item 30. Indemnification

The Registrant's Agreement and Declaration of Trust (the "Declaration"), dated
January 31, 2007, provides that every person who is, or has been, a Trustee or
an officer, employee or agent of the Registrant (including any individual who
serves at its request as director, officer, partner, trustee or the like of
another organization in which it has any interest as a shareholder, creditor or
otherwise) ("Covered Person") shall be indemnified by the Registrant or the
appropriate series of the Registrant to the fullest extent permitted by law
against liability and against all expenses reasonably incurred or paid by him in
connection with any claim, action, suit or proceeding in which he becomes
involved as a party or otherwise by virtue of his being or having been a Covered
Person and against amounts paid or incurred by him in the settlement thereof;
provided that no indemnification shall be provided to a Covered Person (i) who
shall have been adjudicated by a court or body before which the proceeding was
brought (A) to be liable to the Registrant or its shareholders by reason of
willful malfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office, or (B) not to have acted in good
faith in the reasonable belief that his action was in the best interest of the
Registrant; or (ii) in the event of a settlement, unless there has been a
determination that such Covered Person did not engage in willful malfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office.

The Declaration also provides that if any shareholder or former shareholder of
any series of the Registrant shall be held personally liable solely by reason of
his being or having been a shareholder and not because of his acts or omissions
or for some other reason, the shareholder or former shareholder (or his heirs,
executors, administrators or other legal representatives or in the case of any
entity, its general successor) shall be entitled out of the assets belonging to
the applicable series of the Registrant to be held harmless from and indemnified
against all loss and expense arising from such liability. The Registrant, on
behalf of its affected series, shall, upon request by such shareholder, assume
the defense of any claim made against such shareholder for any act or obligation
of the series and satisfy any judgment thereon from the assets of the series.

Insofar as indemnification for liability arising under the Securities Act of
1933, as amended (the "1933 Act"), may be available to Trustees, officers and
controlling persons of the Registration pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant's expenses incurred
or paid by a Trustee, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
Trustee, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.
